[Update (Resolved) – 5:34 AM CST] All servers should be back up and functioning as normal.
[Update – 4:55 AM CST] Some servers are currently down and sites are resolving to a 404 page on those servers while 3rd party datacenter engineers attempt to resolve the issue at hand. More updates as we become aware of further developments.
We’re currently aware of an issue at one of our US datacenters where a large subset of servers in that location have had their file systems set to Read Only. To be clear, sites on those servers are still live and resolving but their filesystem’s are not currently writeable.
We’re working with our 3rd Party Datacenter to resolve these issues and will update this post with more information as we receive it.
