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:
http://useast.ensembl.org is recently launched and provides genome browsing and search facility.
http://uswest.ensembl.org 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.
