As previously scheduled and announced, a new mail server has been brought on line this evening and the current one has been decommissioned.
This is the most complex transition of all the upgrades and there was always a chance, despite two successful dry runs, that a problem may occur. For this reason the work was started on Friday evening to allow a full weekend to fix any issues that might crop up with a minimum impact on customer’s businesses.
The mail service has now been completely transferred to the new server and traffic is currently being routed to it from the old server whilst the DNS changes filter through. This appears so far to have gone smoothly and it seems to be fully operational.
Service disruption during the transition period lasted for just under 3 hours with webmail access being restored after 2 hours.
Close monitoring will continue throughout the weekend and any issues should be reported via the Facebook page or the support contact numbers.
Throughout this year we have been undergoing a series of major infrastructure upgrades with new servers hosted in data centres across three countries.
We have upgraded all our web servers with improved hardware, a choice of PHP versions for each site, free SSL secure certificates for all our client’s web sites and more memory, storage and bandwidth.
Our new DNS servers have also been rolled out so they are located in different countries giving improved resilience. In addition the DNS control panel also includes a host of new features including SPF support.
We will shortly embark on the final stage of the current round of upgrades as our mail server is migrated. As with the web and DNS servers, the new mail server offers improved hardware and software, supporting new anti-spam features and giving all our customers more storage space for their mailboxes.
There has been an “unprecedented” power outage in Amsterdam and surrounding areas this morning that has even managed to close down flights in and out of Schiphol airport.
The data centre that hosts 2 key Webdesigna servers is located in Amsterdam and the data centre is currently running on diesel generators following an automatic failover. Diesel deliveries have been scheduled to keep the generators running and it is not anticipated that there will be any downtime as a result of the power outage.
A team of engineers is currently on site at the data centre so that, should the situation escalate, a controlled power shutdown can be initiated to minimise any downtime.
We will update this when power supplies have been restored or the situation changes.

The power to the data centre has now been restored and the datacenter switched back onto mains power from the generators. No downtime.
Some customers may have noticed a slow down in server response times. We’ve been working with the data centre to resolve a problem with one of our servers that appears to have restricted disk access speeds. Customers with web sites hosted on the evps2 server will see intermittent delays.
The problem has been identified and a resolution is expected today. A temporary solution has resolved the problem for the moment.

Following a day of monitoring the server, performance has been significantly improved on the server now with an Apdex score of around 0.97 throughout the period which is well within the expected performance range. (Apdex is a measure of web page response to the user between 1 which is perfect, 0 which is awful !). We’ll continue to monitor the server.

This problem has now been resolved at the data centre and the server is still maintaining the expected response times. Obviously we will continue to monitor the servers but the issue has now been closed.
The mail server signing certificate expired today and a new one has been created. If you use a secure connection to view your email you may find you get a warning regarding the certificate changing.
To continue using a secure email connection you will need to accept/trust the new certificate.
