Disruptions are now resolved and Ensembl services are back to normal.

We have temporarily disabled Ensembl Tools, for example VEP and BLAST/BLAT on our vertebrate live websites (www, US East, US West, Asia and GRCh37) whilst we investigate a problem with the underlying infrastructure in our Harlow data center. Some of our archive resources are also currently unavailable. We are sorry for the trouble this may cause and we hope to restore them as soon as we can. Other resources such as our FTP site and public MySQL servers are unaffected.

Ensembl is rapidly working towards annotating large collections of genomes based on the nodes of the Earth BioGenome Project. Our aim is to characterise the genome of new species to reinvigorate our understanding of biological diversity, strengthen conservation efforts, and benefit human welfare.
