26/10/2021 Gaps in Gaia EDR3 and Gaia DR3 data

A description and overview of gaps in the data stream that underlies the Gaia data products is given now also for Gaia EDR3 and Gaia DR3. More information on auxiliary data provided for Gaia can be found from the auxiliary data webpage.


25/10/2021 Maintenance period to ESA servers planned

On Saturday 30 October 2021 a maintenance period to ESA servers is planned between 08:00 and 22:00 CEST. Sunday 31 October, any issues appearing will be fixed, so the service might be interrupted from time to time on this day as well.

In practice this means that the following services will be down: the Gaia Archive, all Gaia servers provided through the Gaia team at ESAC and all Gaia DPAC services (except for the content server, certain FTPs and the Gaia Cosmos web portals) will be down.


14/10/2021 Gaia Archive upgrade

On Monday 18 October, the Gaia Archive will be down for maintenance between 10:00 and 13:00 CEST, which will allow to upgrade the Gaia Archive to version 2.13. More information on the new release will become available from the release notes after the Gaia Archive comes back online.
