Update: Disruptions are now resolved and Ensembl services are back to normal.
Ensembl Tools, including VEP and BLAST/BLAT, are currently unavailable as is access to our public MySQL server. There are also problems with some of the Ensembl Genomes sites (plants.ensembl.org, protists.ensembl.org, metazoa.ensembl.org). We are sorry for the trouble this may cause and we hope to restore them as soon as we can.
