Gemini upgrade: planned outage on 1 November 2026

Gemini will be unavailable from 3am to 5am on Sunday 1 November 2026 while we upgrade its database and supporting software. We have chosen this maintenance window to minimise disruption. No action is required from industry users.

During the outage:

• you will be unable to access Gemini or its APIs.
• file processing will pause.

Once Gemini is back online, we will process queued files in chronological order.

If required, we’ll issue ANS messages to keep you informed of progress and any changes to service availability.
