Super Speed Sheffield – Local Business Gets A Speed Boost

Less “information super-highway”, more like “information cart track”

You know how it is, you’re downloading something on the web and your connection starts to grind to a halt and it takes forever to complete

Now imagine that same problem in an office of 20+ staff, who are developing websites, writing mobile apps and uploading them, all with a connection that just about manages 0.5Mbit/s upload speed. This was the problem former KDA office neighbours 3Squared faced when they moved to a larger office to accommodate their rapidly growing team.

Lots of busy developers need a lot of bandwidth

Learning from other people’s web hosting mistakes

As the new series of Dragons’ Den on BBC2 starts it seems that some people in this world are doomed to keep repeating the mistakes of others without learning anything from them.  Every year it is the same without fail, someone will make a pitch to the Dragons and their website instantly becomes unavailable – robbing them of publicity and more importantly, customers.

Even Worse…

It gets even worse when the website is your business!  Last night you may have seen The Present Club do their pitch to the Dragons, like thousands of other people I thought I’d take a look at the website – although more to see if it was still working than anything else.  Unfortunately like so many before they had not prepared themselves adequately for what is probably the largest amount of publicity they are likely to receive in the short term, loosing themselves many potential customers and showing themselves in a poor light to any potential investors – You have to remember that an offer on Dragons’ Den is not binding and may not go ahead once due diligence is completed, but other people may be thinking they are a good business to be involved with (Despite what Duncan Bannatyne may think, you need to keep your options open to get the best deal if things don’t work out).

What can be done?

If you find yourself in such a situation, where you’re going to appear on TV, or your product/service will be featured prominently on Radio/Magazine/Large Event then you need to talk to your web hosting company as soon as possible and ask them what they can do to help you cope with the increase in visitors to your site – of course some of these things will not be free, but as a business person you have to work out the cost of lost customers.

The Maths

If your appearance on TV brings in 200,000 visitors to your site and you usually convert 3% of visitors to customers then that’s 6,000 new customers for you – But only if your website is up and running.  Maybe 5-10% of those will come back the next day to take a look at your site, so now you’re only talking about 300-600 new customers – that’s a significant drop.  If your average sale is £20 then that’s a difference of £114,000 at the worst case (£120,000 – £6,000).

Can You Afford To Throw Away £120,000?

If so then you probably don’t need to be reading this blog post at all and congratulations, you’ve done very well for yourself.  If like the majority you can’t then you need to sit down with your web hosting supplier (or better yet, give us a call about our business web hosting and dedicated servers) and work out a plan – even if it’s only for a temporary increase in capacity for your website.  There are a great many things that can be done, quite a few of them for free that can help your website survive an increase in visitor numbers and help you capture new customers – for <1% of that £120,000 of new business you could potentially increase the capacity of your website by 3-4x, if not more in some cases.

Secure Offsite Data Backups – For Servers and PCs

How do you backup?

Hopefully the answer isn’t “we don’t”, hopefully you at least take backups to a server in your office, or to disk and keep it in a fire safe.

Data is the key to all businesses, without it there often is no business left, or it soon goes out of business quickly after a data loss – so looking at backups is something you should do right now if you haven’t, and if you have then you should review the situation every year to make sure your current system still meets your needs. Could you survive without payroll data? Without your customer lists? Without your inventory data? Without your emails? Work in progress?

Not just servers

It’s not just servers you should think about taking backups of either, more often than not employees will store critical data on their desktop and laptop PCs, even if company policy says not to. Even if all of your data is stored on a server, you need to think carefully about where you back it up to – we’ve seen a lot of people fall in to the trap of, “Well it’s got RAID so it’s fine” or “It’s got a USB drive attached to it” and leave it at that. RAID isn’t a backup mechanism and a locally attached USB drive isn’t going to help when it’s burnt to a crisp with your server, under 2ft of water or in the back of someones van!

We have the solution!

This is where we can help you, we are proud to announce the launch of our new Protexia® DataSafe backup service providing affordable, secure data backups for servers, desktops and laptops.

  • Secure: Files are encrypted before leaving your machine with AES, TwoFish or 3DES and sent to us over a secure encrypted data connection
  • Fast: Files are compressed before sending, only changes are sent
  • Flexible: You can have multiple backup sets with different backup schedules and retention policies
  • Cross Platform: Supports Windows, Linux and Mac
  • Easy To Use: Windows and Mac have easy to use graphical interfaces for managing backups from the machine and all clients get a web based interface for managing backups and restoring files
  • Databases: Supports backup of MS SQL, Oracle and MySQL Databases
  • Email: Supports Lotus Notes and brick level MS Exchange Backup

We are providing free 30-day trials of Protexia® DataSafe with 50GB of storage space ahead of our full launch. Once you’re happy with the service at the end of the trial you would pay:

  • £20/month + VAT for the first 50GB
  • £15/month + VAT for subsequent 50GB blocks

If you have any questions about the service or backups in general then please contact us.

.uk Short Domains (and Reserved)

As many of you will already be aware (we’ve already applied for some of you) Nominet (the organisation that runs the .uk domain name space) is releasing a large list of previously reserved domain names – most of these are either single or double character domains. At the moment we’re in the open landrush phase – so anyone can apply for any of the remaining 2640 domain names.

How much does it cost?

Nominet charge a fee of £10 + VAT per domain name for applying for a domain name – if you’re the only one that applies then you’ll be allocated the domain name, if more than one registration is received by June 15th then it will go to auction. If you’re successful at either stage then KDA will charge our usual fee of £14.95 + VAT per domain name to register it for 2 years.

How do I apply?

If you’d like to apply then you’ll need to open up a support ticket with us, as we’re currently doing all the reserved domain applications manually – so we can make sure everything runs smoothly. Once we’ve submitted the request, we’ll send you a code, which you’ll need to enter at the URL we provide – this will allow you to pay the £10 + VAT fee to Nominet.

Upgrades and Additions

We’ve had a few people ask us exactly what we were doing in our recent scheduled downtime sessions during April, so here we are:

New Datacentre Facilities

The main bulk of the time has been spent moving the majority of our servers from our current point-of-presence (PoP) at Interxion in central London to our new PoP at London Hosting Centre in the Docklands area. There are a number of reasons for this move, which we weighed up very carefully with the inconvenience that would be caused to you:

  • Inability to get extra power to our racks – we were running them half empty as we could not get extra power without moving our equipment to a different part of the building.
  • A change in focus for Interxion – they are moving towards fewer, much larger corporate customers.
  • Above market rate pricing – year on year we have absorbed price increases, unfortunately the latest price increase we would have had to have passed on and would have resulted in prices rises of between 15-25% for you, this is not something we would have been happy doing and something a number of you told us you wouldn’t want to pay.

When we weighed up these 3 main factors we took the decision to find alternative facilities to run our services from, we are confident we have made the correct choice of facilities. We have always set out to work with partners for the long term, working as we did with Interxion for over 7 years.

The eagle eyed among you will have noticed a plural in the above statements, that we have chosen facilities to work with, not just a facility. Our network and services are now present in 3 geographically diverse datacentres, along with London Hosting Centre we have setup PoPs in:


We are now present in Manchester, with our first services planned to go live during May (more of which below). We take network connectivity in Manchester from two providers, as well as having a gigabit link between Manchester and London.


We also have a presence in the Sentrum IV facility in Woking. This is a highly secure, Tier III+ facility providing excellent options for customers who need to be outside of London, but not so far outside that it causes them major travel problems.

Network Upgrades

A major part of our work has been to upgrade our network so that it is now Juniper powered in the core and distribution layers. For LHC this means using the latest Juniper MX80 3D line of routers and EX4200 switches. For Manchester this means Juniper J-Series routers and EX4200 switches. Woking is currently connected via diverse Layer-2 services back to LHC for routing – as any network connectivity in to the building is predominantly back-hauled to London first anyway, so it would currently serve no purpose carrying out routing from there.

As time passes, the needs of the facilities change and traffic levels increase we will be reviewing the equipment used at each facility, with the plan being to bring them all in-line with each other utilising the Juniper MX 3D series of routers.

Gigabit for all

During the move to LHC we took the opportunity to replace the last of our 10/100 switches and replaced them all with new 48 port Gigabit capable switches – all existing customers will now find they are connected to our network with a Gigabit port if their equipment supports it – a free upgrade that many providers charge monthly for!

IPv6 Support

A major driver in replacing all of our routers has been IPv6, it is something that has been long overdue in its implementation on our network and will be formally rolled out in June. Unfortunately many software vendors still aren’t supporting IPv6, so this does mean that for some services we still won’t be able to support IPv6 – unfortunately one of those vendors is cPanel, so for the time being our shared business hosting still won’t support IPv6. This is something we are putting pressure (along with many other companies) on cPanel to implement as soon as possible.

Increased connectivity

We’ve increased our public Internet facing network connectivity by 100% in anticipation of take-up on our new services and also to match ever increasing broadband speeds.

The Future…

We’ve got a couple of new products on the way in May, as well as making some changes to the way we do certain things – but you’ll have to come back later to find out about those :)

Network Upgrades

On the evening of Saturday 16th April from 22:00 we will be performing essential network upgrades and maintenance. This is work that we hoped to have completed before we began moving any equipment from one facility to another, but unfortunately due to lengthy delays in the supply of some essential equipment this was not possible.

As part of this work we will be installing new Juniper Networks routers and switches to upgrade our routing capability. For the curious amongst you we will be using Juniper MX80 and EX4200 routers and switches.

The main bulk of the work that is service affecting will be migrating customer VLANs from the old routers they are terminated on, to the new equipment. The impact on service should be no more than 5 minutes per VLAN in two phases and we expect much less if everything goes to plan and as per our testing.

Please accept our apologies for the relatively short notice of these works, we would not be performing them at this time if it were not 100% necessary at this time. If you have any questions at all please do let us know.

VAT Changes

Just a reminder if you didn’t know already that UK VAT rises from 17.5% to 20% on the 4th of January (first working day of the new year). This means that if you currently pay us £10 + VAT or £11.75 including VAT, your invoice will now come to £12.00 including VAT.

You’ll also need to remember to update your own shopping carts/ecommerce software if you’re using any to take account of the new rate of standard VAT from the 4th of January – if you don’t, then you’ll end up 2.5% out of pocket – as the VAT man will still want his 20% even if you only charged the customer 17.5%.

Linux Vulnerability CVE-2010-3081 – Local but serious

As many of you will no doubt be aware there has recently been a vulnerability with 64bit Linux announced that allows a local system user to gain root level system access. Whilst these things do happen from time to time, the problem at the moment is that a lot of vendors do not have a new kernel with the security hole patched. To make things worse, the exploit that is out in the wild installs a back door in to your systems as well, so even when patched they will still have root level access to your system!

Whilst many are saying this isn’t a major issue as it is only exploitable by having local machine access, it’s actually bigger than a lot of people realise in a web hosting environment as users are allowed to execute their own PHP and Perl code or install 3rd part scripts – what we’re seeing lately is that many such user and 3rd party applications have many holes in them that allow arbitrary code to be executed or even uploaded on to servers and then executed. Both situations effectively give a local user account (that of the web server user, or the account user depending on how the system is configured). One of the biggest causes of such problems are scripts that allow users to upload images or other files to a website – the vast majority of them do not check to make sure it is an image, or a PDF or a text file etc. that is uploaded – we’ve seen recently that a lot of these scripts allow users to upload PHP scripts for example instead of an image and of course once it’s in the images directory it can be executed like any other PHP.

There is currently a workaround for the specific exploit out in the wild, but they do not protect from any new exploits that may utilise the same security hole. The only solution ready at the moment appears to be that from – Which our managed hosting customers will be pleased to know we’ve been installing on all of your servers for the past few weeks now. For our un-managed customers you can also have KSplice but unfortunately for you there is a small charge for this, of £2.50 + VAT per copy – If you would like it installing then please open a ticket with us and we’ll get it done for you ASAP.

Phone calls about SSL renewal – Misrepresentation

Unfortunately it’s a sad sign of the times that we’ve had customers report to us that they are getting calls about renewing their SSL certificates they have purchased through ourselves – there’s nothing unusual in that you might think, but there is when they are claiming to be from either ourselves or the issuing authority for the majority of our SSL certificates (Comodo).

What we’d ask is that if you do get such a call, you find out as much information as possible i.e. telephone number from them, email address or what company they are really calling from – as obviously we don’t like people fraudulently mis-representing themselves to our customers and we don’t want our customers being sold sub-standard certificates or getting a sub-standard service for their SSL certificates.

So please, if you’ve been contacted or get contacted let us know. If you’re the company behind this and you’re reading this then I’d quit whilst you’re ahead :)
