21 May 2019 - Upcoming Downtime: ArrayExpress submission system will be unavailable on Thursday 30 May 2019

Due to essential maintenance, we'll have to shut down the ArrayExpress submission tool Annotare on Thursday 30 May. Unfortunately, uptime of ArrayExpress may also be affected.

We would like to ask submitters to log out of Annotare before the maintenance period, and return after the weekend to continue with your submission. All information entered and files uploaded in Annotare are automatically saved, so rest assured that nothing will be lost.

We hope to keep the downtime to a minimum and hope to return to our normal service again from 31 May 2019. Follow our Twitter feed for real-time updates. Sorry for any inconvenience this may cause.
