It appears that 123-reg are having some network problems today. The cause was a distributed denial of service attack from China starting around 11.30am according to the 123-reg website service page.
Some users report having temporarily lost their websites and users were unable to access to their 123-reg control panel and webmail during the outage.
123reg said that “Due to the nature and size of this attack the firewall systems in place needed to be reconfigured to block the bad traffic and allow the good traffic through. Our 24/7 network team picked up on this straight away and started to make changes to bring services back online to the Internet“.
They also added “Things may be a little slow over the next hour or so as we continue to configure the systems to effectively stop the attack. Thankfully, as the largest UK hosting provider, 123-reg has the data centre and team in place to combat these Internet criminals with minimal damage“.
These attacks are by their nature a bit of a nightmare so my sympathies go out to the engineers at 123-reg who have had a stressful morning. The good news is that things appear to be getting back to normal.
