Heh, seems to be a weekly/weakly thing. From HMEM, 2011/01/18, at 23.56 GMT.
"Forbidden
You don't have permission to access /index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request."
Seems to be a recurrent problem there. Last time it was an attempt to hack HMEM proper. This time it might be something to do with another site that is hosted in the same servers, which has wreaked havoc on someone's nerves. I can't imagine why anyone would really want to close down HMEM proper. But there's lots of things I can't imagine...
Tough luck, not much that can be done about it, except change providers.

P.S. If you're wondering whether it is because of the (HMEM) site, or if it is in your machine/connection, one way to make sure is to visit and use
http://www.downforeveryoneorjustme.com/There are many other similar sites to check on a possible problem with some website. This works fast, at least here
