Elevated 401 Response returned for multiple chains

Incident Report for Alchemy

Resolved

From approximately 08:30 UTC to 09:30 UTC we experienced degraded performance on a subset of networks which would have manifested downstream as an 'Authentication failed' error. This impacted our Wallet Service and Subgraph products as well. Mitigation efforts have been completed and services are operational.

We sincerely apologize for the disruption this may have caused.
