2:30pm Pacific / 9:30pm GMT — We received an update from Microsoft on the implementation of the fix for the issue causing digests to be rendered incorrectly. From their communication: “Upon further investigation, it was determined that additional infrastructure is affected by this issue. The deployment of the fix that is already in progress will be extended to cover this additional infrastructure to completely remediate impact. Affected users will continue to experience incremental impact remediation as the deployment propagates throughout the environment.”
We have seen that the issue has been mitigated to some extent, but do not have a good way to measure progress of the fix deployment within the Office 365 infrastructure. We will continue to post updates here as more information becomes available.
