As I'm sure a lot of people will have noticed, there have been a few short blips in the servers performance and stability today, this was a result of upstream network issues and ultimately an unexpected impact to config changes that were being made on the underlying host which for a short period resulted in no network access to the host.
The incident is on https://status.atlas-media.co.uk/incidents/yUUmeL2O2D8N and I'm not expecting any further issues now.
Apologies for any inconvenience.
