SIGN DE v2 degraded performance on signing requests

The remaining issues have been successfully resolved, and response times are back to their normal levels.
All systems are now working as expected. 🎉

We sincerely apologize again for the inconvenience caused and thank you for your patience and understanding during this incident.

We are back at full performance for most TSS. Unfortunately, a small number of TSS are still experiencing degraded performance. Our team is working intensively on analyzing and resolving this issue.
We apologize for the inconvenience and appreciate your patience.

NOTE: Don’t block the till
There is no obligation that the till should stop its operation or be heavily affected at any point in time.
Please make sure that your integration is not blocking the operators.

The issue appears to be contained for the majority of TSS requests since 16:10 CEST (14:10 UTC). The team is still monitoring the situation, but for now signing performance is back to normal.

Due to issues after the maintenance operation on 25.08.2025 and 24.08.2025 some of the TSS might still experience degraded signing performance. We are currently working on a solution to mitigate this issue.
