Well, as a service operator myself (though without any responsibility to PrimeNet), I do try to warn users when a service is at unusual risk. As for crashes, or unplanned outages for other reasons (like the power failing), I would try to post a notice explaining what happened as soon as I know myself. In the case of a system which fails on a Friday evening I do not think it is unreasonable that there is no information until Monday. Presumably the system support staff are not paid on a 24x7 basis. BTW some people claim that the PrimeNet server is working, just very, very slowly. In that case it's more than likely that the server is sufferring a DoS attack :( Such an outage didn´t occur for the first time in my (nearly) three years supporting GIMPS and others will follow. Is that a statement, or a threat? BTW I do remember a few service breaks, though this one is the worst; in fact the service has been pretty reliable recently, at least until last Friday night. May be that´s one reason why GIMPS lost about 8.000 to 9.000 machines during the last six months. Other reasons may apply: (a) new projects which may be attractive to many people; (b) the increasing size of our work units; processor speeds really haven't been keeping up! (c) problems with utility (mains) power supply in some areas e.g. California discouraging people from running systems 24x7; (d) adverse publicity involving distributed computing projects e.g. the sysadmin who installed RC5 clients on his systems without consent of his employer.

Re: Mersenne: Prime Net Server
The thing is that even a 2-3 day outage is no big
deal, because if we are all responsible GIMPSers, then we have our "days of
work" configuration set to more than a couple days worth, right? So the
worst that should have happened is that you have a result to check back in and
have to wait for that while the next number is already crunching.

I
beg your pardon: you didn´t really expect to get informed about a planned
outage BEFORE it happens or a crash AFTER it happened, did
you?
If
you did expect this, then you should have joined another distributed-computing
project like SETI. They do inform their participants about such things. But
people who are cool enough to find million-digit-primes should be able to find
out that the server is down the whole weekend. Well, you have to pay for
it (in Germany), but who cares?
Such
an outage didn´t occur for the first time in my (nearly) three years
supporting GIMPS and others will follow. May be that´s one reason why GIMPS
lost about 8.000 to 9.000 machines during the last six
months.

Re: Mersenne: Prime Net Server
Hi, it isn't that easy at all. The default parameter for networkretries is, afaik, 10 minutes. So most clients try to connect every 10 minutes until thy got a timeout. And the timeout seems to be very long :-/. I think we loose much power on these gimpsserver fails.

Re: Mersenne: Prime Net Server
Aaron, you´re right. I had to check in a result and if you have to use the manual way to do this and if you have to pay per minute for every internet connection than it´s wiry that the server is down for days and nobody told you that this was planned or not planned and when the server will be available again.
