Dear Customer,
We have sadly seen this issue reoccur. We have been in conversations with our upstream network provider to get this issue resolved as quickly as possible.
Upon investigation into the issue, it appears that the 10gbps cross links in the switch is crashing, whilst keeping the 1gbps connections online. A replacement switch has been ordered. This issue lies with our network provider, not ourselves, but we are assisting where we can to help resolve the issue.
We do apologise for the inconvenience, and hope that it can be resolved as quickly as possible.
