This issue was opened retrospectively.
During the period of 15:03 to 15:12, we experienced an issue with connection terminations on our access router layer.
Connectivity was restored and connections are coming online. Due to increased load on our RADIUS servers, authentication of your router(s) may take longer than normal.
We are working as a top priority to identify the root cause of this issue, and an RFO will be available once ready by emailing our support team at firstname.lastname@example.org.
We deeply apologise for any inconvenience this outage caused to your Monday afternoon and will work to ensure this issue does not re-occur.
