Update

The continued Canvas outage is now affecting various member institutions' data exports needed for the nightly UDP ingest and will result in fresh data not being present in the UDP tomorrow.

Monitoring

We are starting to see Canvas caliper events begin to flow. We will continue to monitor our endpoint and the event volume while the underlying AWS issue is fully resolved.

AWS has reported the following:

Our mitigations to resolve launch failures for new EC2 instances are progressing and the internal subsystems of EC2 are now showing early signs of recovering in a few Availability Zones (AZs) in the US-EAST-1 Region. We are applying mitigations to the remaining AZs at which point we expect launch errors and network connectivity issues to subside.
