All services are currently down unexpectedly. A problem occurred on our nodes which completely bottlenecks and restricts PHP and nginx activity, so we are currently working on debugging this, which is a bit hard as it produces no errors, either, other than a 500 response code. This should not affect any customer sites, but it may produce some errors as they cannot connect to apantic.com to check branding related information.
We will provide further information when we have it. At worst, we plan to take a database backup, which we have, and rebuild the VPS from scratch.
Thanks for your understanding,
The Apantic Team
