Resolved after 1 hour 41 minutes, affecting Time Stamping, on September 25, 2026.
The problem with the failing TSA server has been resolved and we are continuing to monitor the situation closely to ensure no more errors occur. The problem resulted in a small number of spikes in HTTP 503 responses, across all TSA services. This caused a small number of upstream errors to be returned by DSS as well.
