We regularly upgrade and backup systems nightly and most often with no known impact to the network, servers or portals. If a Geo Datacenter is impacted (Vancouver, Calgary, Ottawa or Montreal), we will automatically fail over prior to the maintenance to ensure calls are not impacted.

We are experiencing issues with call quality, and our Engineering Team is investigating. We will update as soon as we get more information.

We've confirmed the root cause, and we are currently monitoring it.

We've now resolved the incident. Thanks for your patience.

We are seeing additional sporadic lower MoS scores in the past 45 minutes. A dozen switch engineers are investigating live, but it looks to have stabilized. A full post-mortem will be issued later today, once the identified cause has been confirmed.

We've confirmed there is a problem and are working to resolve it for improved call quality during the recovery. All calls are progressing and always were during the period of lower call quality yesterday and this morning.

This incident is resolved. Thanks for your patience.

We are currently investigating a report of Portal not responding. We'll update soon.

We've fixed the core issue and are waiting to recover. Our team is monitoring. We see a full recovery; calls were not interrupted or devices unregistered as part of our initial observations. A full post-mortem will be posted soon.
