Couldn't connect to database hgcentral on hgnfs1-c as hgcentuser. Can't connect to MySQL server on 'hgnfs1-c' (115) We hate this error more than any other and may be already looking into it.<br> If there is no message on https://twitter.com/GenomeBrowser with the time when we expect it to be back: You can help us by telling us about the error, our email is genome-www@soe.ucsc.edu. We will fix it ASAP.<br> And even if this server is failing for a few more hours today, usually, one of our other three international mirrors is still working. The three mirrors are genome.ucsc.edu (US), genome-euro.ucsc.edu (Germany), genome-asia.ucsc.edu (Japan). You may not find your custom tracks and saved sessions there, but using another mirror should allow continuing your work while we are fixing the problem.
