At 12:19 CEST Thursday 19th of September, we experienced a partial outage on the telephony channel with reports of customers being unable to make calls and incoming calls failing.
We immediately initiated an investigation and found an issue with one of our upstreams suppliers that caused delays in data being sent to Dixa for call verifications. These delays caused timeouts which had the effect that numbers became unavailable to use for outbound calls and either caused inbound calls to take longer to connect than usual or to fail entirely.
At around 12:40 CEST, error rates were going down rapidly and the incident was changed to monitoring at 12:52 CEST after some time of stability.
We sincerely apologize for the inconvenience this caused
