It looks as if 123-reg.co.uk have major problems with nameservers/DNS records.
I noticed a problem with a CNAME that wasn’t working during the week but thought nothing of it. Last night I noticed that all my sites were down. One of them is still on TextDrive so I knew it couldn’t be the server itself.
This morning I checked again and yes all still dead. Even the support site 123-support.co.uk is not responding, no surprise there, but I managed to find a 123-reg.co.uk Problems and Compaints forum and read that a lot of people are in the same boat. Thankfully I’m not loosing money because of the downtime but quite a few people are. They have perfectly functioning web-servers that no one can access.
123-reg.co.uk posted this on their system status page at 09:15 this morning:
We are currently aware of a problem regarding 123-reg nameservers which in turn is affecting the visibility of websites and services such as email. At present, we have engineers looking into this as a matter of urgency. Please be assured we are working to rectify this issue as a priority and hope to resume normal service as soon as possible. Thank you for your patience in the mean time. We apologise for any inconvenience caused.
Luckily for me my host, Slicehost, allows you to set-up DNS records for your domains. It was a bit laborious entering all the web and email settings but now that I’ve switched nameservers at 123-reg.co.uk everything is back up and running.
