Hmm, one could put a short TTL on the DNS entry, and swap it to point to another machine in case of problems.
However that could be problematic in terms of hugely increasing traffic for the DNS server.
I tried this several times... i don't think it is a good idea. Isn't it possible to do a normal port-forwarding while doing some work on the server?

We would have to initiate this from the machine that is not responding, or we would have to have a router under our control connected upstream.
The former, of course, won't work when the machine is not responding, at least until we know why the machine stops responding (in which case we don't need this solution anymore). The latter exceeds our current budget of $0.00.

It does not have to be that complicated. In principle, and if we assume that client browsers support the META redirect tag (after, say 120 seconds), than a wikipedia mirror could welcome everybody who thirsts for knowledge, no ?

I thought that the server is down for maintenance because someone is installing new software? So portforwarding would be possible....

And what about temporal moving to a rent server for some ours ( short-time rent room).
Made the changes, the wikipedia could return to the original server.
This is interesting to see with http://www.wikipedia.org/wiki/interwiki servers interconnected.

Ah, in this situation, I agree that such a thing would be easy to do. Our most recent outage (night before last) was due to server problems that we don't comprehend at the moment. Since this thread began the next morning, I assumed that that was the type of outage we were attempting to deal with.
For outages like these, it only takes a few moments to fix, assuming someone calls me and asks me to (760-486-9194). Other than that, I don't think there is an easily workable solution.

I'm getting the feeling that I misunderstood what everyone meant when this thread started. I thought we were talking about times when we have lost all contact with the server, but it seems that most everyone is talking about when the server is not responding due to some sort of maintenance (do we even do that?).
All I ever meant to say is that if we can't control the server at all (that is, we can't login, and it doesn't serve any webpages), it is unlikely that we will be able to perform any sort of redirect without bringing in some new equipment to preempt the connection. Also, in this type of situation, it only takes me a moment to restart the server once I am made aware of the situation, so it would be easier and faster if somebody called me and told me instead of trying to redirect all traffic from the server...
