We’ve just set up an externally hosted blog at http://blog.discogs.com
This will be used to post updates about the site status such as emergency problems, slowdowns, etc. That way you’ll be able to get information if there is a problem while Discogs may not be available.
There’s also a link to this blog on the “our servers are overloaded” page which you may see sometimes right now. And there’s a post on the blog explaining the current problems.
