Yesterday this site appeared to go entirely offline for quite some time, also reported by many other Twitter users by searching "LCPDFR", with a "Server Not Found" error.

 

There has been no Twitter posts about it nor any posts here. Just wondering what happened? 

I had the same thing all day, I then messed around with my DNS server settings and the site started working then. 

We had a DNS outage for about an hour on Saturday night, at around 11pm BST. Because of a configuration issue, we had to change the IP addresses of our DNS servers. We had everything fixed around 1am on Sunday morning.

We saw traffic recover to around normal levels a few hours later at around Sunday morning 6am.

 

Some choice ISPs DNS resolvers that cache information for far too long (which is probably around 5% of our visitors) would probably not have been able to access the site until their caches cleared. Anyone using a decent DNS service (like Google DNS, Cloudflare DNS or just decent ISP resolver) wasn't affected for longer than an hour or two.
