That's scary: are there any off-site backups of the full database, including the article text, made anywhere, other than the constantly failing dumps? Given that Wikipedia is the Wikimedia Foundation's principal asset, I would hope that fixing this single point of failure would be a priority for the Foundation.
Yes, all databases are replicated to another cluster located in amsterdam.
But you are right: the situation does suck. We got the new hardware to get working dumps again now, we just have to sit tight and hope this fresh dump of enwiki works. If it does, things should go smothly again.
