Is NoPrimeLeftBehind off-line? I cannot reach it and all my boxen have run out of work.
Yeah, we're having some as-yet-unknown server troubles right now - see the "Server outrages" thread at the NPLB forum from post #362 on. Gary's out of town right now, so we don't know yet what the exact problem is.
Based on the evidence we do have, it looks like it might be a router issue. Gary may be able to have a friend go over to his house and restart the router and/or server, but if that doesn't work it will have to wait until he gets back in about 1.5 weeks.
In the meantime, I'd recommend configuring PRPnet backup servers so your machines are still doing useful work - I have a few PrimeGrid servers configured on each of my boxes for when NPLB is down (which lately has been fairly often...we're working on figuring out what's going on with that).
