Some of you had noticed/reported that inbox.sourceware.org was becoming slow. And indeed crawlers had found it and were hammering it. We have put Anubis in front of it and it seems a little more responsive now.
Like all other Anubis wrapped services this is using the "metarefresh" challenge (which is a non-javascript based challenge). Sadly it seems more and more bots are learning this trick. So we might have to switch back to a javascript based challenge (for suspicious browsers or ip addresses). Please do report if you have any trouble accessing any Anubis wrapped services.
