Previous incidents

We have had no further reports so are closing this issue. We continue to remind customers our Xneelo voice infrastructure is already end-of-life, and customers should have already received communication to move them on to Azure.

We are closing after several hours of stability being observed.

As we have now received confirmation from Microsoft the issue is deemed resolved from their side, we are closing this issue. We will await further RCA from Azure, but their current provided Root Cause is an unexpected increase in traffic - most likely a large scale DDoS attack given the number of regions affected.

Current status: Our monitoring telemetry indicates that the issue has recovered. We're continuing to actively monitor the environment and perf...

We plan on moving all clients currently on Xneelo to Azure given the recent stability of Xneelo.
