Problems with one upstream provider Degraded

We have noticed problems with an upstream provider that we believe are related to an aggregated link within their network.

We took the affected provider out of service, and monitored the situation.

Subsequently service seems to have been fixed. We are now awaiting feedback from the upstream's network operations team.
