On January 07, 2024, at 08:29 UTC, we identified several backend services encountering errors due to network timeouts in Anaplan Amazon Cloud – Dedicated, which resulted in customers not being able to load workspaces.

We identified that the issue was caused by the patching activity carried out by our vendor, AWS (Amazon Web Services). AWS confirmed that the automated upgrade process had populated incorrect entries into the routing table during the upgrade. AWS manually rectified the routing table entries to mitigate the issue, and service was restored at 12:18 UTC.

To avoid a recurrence of this issue, AWS has confirmed that steps have been taken at their end to ensure that this issue does not reoccur.

We apologize for any impact this issue might have had on your business operations. We are continuously strengthening our systems and procedures to ensure we avoid future disruption to your business and users.
