Disruption to Ensembl services

Due to scheduled maintenance work, a number of Ensembl services will be temporarily unavailable between Tuesday 26th July 2022, 15:00 (BST) and Wednesday 27th July 2022, 13:00 (BST).

The following services will be unavailable while the work is being carried out:

  • Tools and accounts on all Ensembl sites including the main Ensembl site, mirrors, GRCh37 site and Ensembl Genomes non-vertebrates sites.
  • All Ensembl web and REST archives

It is also likely that other services, including the main Ensembl site, mirrors, GRCh37 sit, Ensembl Genomes non-vertebrates sites and REST API will experience slower response times while the work is being carried out. Services will be resumed as soon as the work has been completed. If you have any questions about the planned maintenance work, please contact us on the Ensembl Helpdesk.


  1. Is this disruption still on going? I have an error message 28/07 08:00am BST

    MSG: Cannot connect to the Ensembl MySQL server at ensembldb.ensembl.org:3306; check your settings & DBI error message: Can’t connect to MySQL server on ‘ensembldb.ensembl.org’ (110)

    1. Hi Naomi,
      The planned maintenance work is completed, although the error you are experiencing is the result of some teething problems once we switched everything back on. We’re working to resolve this as quickly as possible. Thank you for your patience.
      Best wishes
      On behalf of the Ensembl team
