Please be advised that there will be a scheduled system session affecting the LUMI & MN5 polytope service on:

      Date: Thursday 23rd July 2026

      Time: 11:30 – 13:00 CEST (1.5 hours) (10:30 – 12:00 BST)

Impact:

• Active polytope requests will be allowed to finish but polling of their status will fail for the duration of the session while the service is offline.

• Queued polytope requests may be lost as part of the session.

• Polytope requests will not be able to serve data from the data bridges during this time.

Reason for Maintenance:

This session will be used to provide an upgrade to the polytope service, bringing improvements to throughput and handling of both large and small data requests.

We apologize for any inconvenience this may cause and appreciate your understanding. Please plan your activities accordingly.
