Monitoring

Our telephony services have largely recovered, and overall service availability has significantly improved.

While most services should now be operating normally, some customers may still experience isolated connectivity or calling issues.

Our technical teams are continuing their efforts to fully restore and stabilize all affected services while closely monitoring the situation.

Once service stability has been fully restored, we will conduct a comprehensive root cause analysis and identify measures to help prevent similar incidents in the future.

We apologize for the disruption and appreciate your patience and understanding.
