As Anne mentioned, at approximately 03:00 UK time on 2 July, the Sanger Institute Data Centre suffered a power failure. The effects of this have taken taken the main Ensembl web site and other resources off line. We are working to get the services restored.

In the mean time, we have two US mirror sites available: is recently launched and provides genome browsing and search facility. provides genome browsing, but search relies on the main site in the UK.

Please note that BLAST services require the main site at Hinxton and will not be available until the systems have been restored.

Thank you for your patience and we apologise for any inconvenience caused.

We are currently experiencing further system problems caused by a generator failure at approximately 3am UK time. Our IT staff are working to restore service, and we apologise for any inconvenience caused.

Our US mirror,, is still available, although features that depend on Sanger services (user accounts, BLAST) will not be working.

We are currently experiencing a power failure which has taken the main Ensembl site offline. Our mirror site is still running so please use this until we have the main site back online.

BLAST should be available again – following the recent scripting, the server hard drive had filled up, so that it was unable to process any more requests. We have cleared some space, so the server is now able to accept tickets once again.

Please accept our apologies for the continued downtime.

Our BLAST/BLAT service has been re-enabled, following a problem with the server hosting the BLAT logs which has now been fixed. Thank you for your patience.

We have had to disable BLAST temporarily owing to excessive load on the servers. The service will be enabled as soon we have analysed the problem.

We have now repaired the BLAST database and the service is once more available. We will be monitoring the situation, but hopefully no further action will be required.

Please accept our apologies for any inconvenience caused.

We regret that owing to problems with our BLAST server, we have had to disable this feature temporarily, as issues with tickets were bringing down the whole Ensembl website. We will endeavour to have BLAST back online as soon as possible; please accept our apologies for any inconvenience caused.

We are currently in the process of releasing Ensembl 56, and should be back online within an hour or so.

Please note that all Ensembl-based sites will be offline at this time whilst we upgrade our user account database. Affected sites include Vega, Pre, the Ensembl archives and the US mirror. Please accept our apologies for any inconvenience caused.
