Server Downtime News Update

An update on the frustrating downtime this morning. I upgraded the server last week to include a more robust managed back-up system, this meant the folks at Rackspace had to move the server to a new location (with a new IP address). I asked them to do this at midnight this morning to minimise inconvenience for all. However… they forgot to update all of the IP addresses on the domain A records so they were still pointing to the old server IP address up until about 7:30am when I contacted the technical support staff to identify the problem.
By 9am the IPs were fully restored. After a further Plesk update by Rackspace at 11am, all web, database and email was fully functional across the major ISPs (some like BT take longer to spot the new IP address than others), hopefully all now back to normal for everyone. Sincere apologies for the inconvenience this morning. Firetop hosting customers should let me know if they have any unusual problems. If you would like to know more about DNS caching delays on individual ISPs, I recommend this article at Wikipedia.
Server downtime is flagged up to me by SMS alert and email (gmail) if a contact cannot be established for longer than 15 minutes. I had an alert at 1am but was expecting that, what I didn’t expect was to wake up to the downtime later on in the morning 
This is only the second short period of downtime in two years so I like to think we’re not doing too badly over all.
