The Wellcome Trust Genome Campus as well as the Sanger Institute and the EBI are closed for the holiday period between 23 December and 2 January. Ensembl browsers (www.ensembl.org, useast.ensembl.org. uswest.ensembl.org. and asia.ensembl.org) along with underlying databases will remain accessible during this time, however, if we experience any issues, associated fixes are likely to be delayed.
As usual, API or local installation issues can be reported to our developer mailing list (the archive is searchable at http://lists.ensembl.org/pipermail/dev/), and questions or reports about the browser or underlying data can be emailed to helpdesk (this is a private list). However, please expect delays in replying to your question up to 4 January 2013.
Have a good end to the year. We look forward to hearing from you in 2013.
