The issue has been resolved now.

Delegators Table, Profile Delegations Table have now been restored.
However, Profile Delegation Chart and Totals are still actively being worked on by the product team.

We are currently performing scheduled software updates on the Upgrade Indexer.

At this time, we do not expect any customer impact as a result of this maintenance. All services should continue operating normally.

Our team is actively monitoring the process and will provide updates as needed. We will share a final update once maintenance is complete.

Thank you for your patience.
