Have you seen the level of demand on the Cricket graphs is still very high. This shows the system still settling down, and drawing 92+Mbps bandwidth.

Can this demand go on, or will the servers collapse under the strain?
It's good to be back amongst friends and colleagues

Offhand, I'd say this looks solid so far. The recent trend has been somewhat less than half the outage time at 90+ bandwidth before starting to tail off.

My recommendation; Panic Off for now. :-)

If it lasted this long, then there's no reason to think that it'll fail because of overload... other factors seem to be the cause.

It's interesting, that the area of the peak above average should be roughly the same as the area of the gap in the chart...

Looking at the graph the servers have coped remarkably well catching up with the backlog and only now is the throughout starting to reduce indicating the worst of it is over for them.

Interesting, even though we've dropped down quite a bit, we're still running above normal and increasing over the past week. We started at about 35MB after the recovery from an outage on 25 Mar, and are currently running 60-65MB (as of this post).

This link displays activity a little clearer.

Actually, I would say that the current level is closer to 'normal'.

Coincident with the installation of the new router, Matt found a stash of tapes which split to provide almost exclusively long-running WUs. Now the shorties are back in the mix. We get through them quicker, so more have to be sent out to keep our shivering cores warm, so the bandwidth goes up - to about the level the old router maxxed out. Now, we have a bit of spare overhead for recovery too.

Things look better at my computers. Fewer "Ready To Reports" and a fuller cache than yesterday.

Or at least enough so that our farm PCs will keep our houses warm. ;)

Minor problem- looking at Scarecrow's graphs only the Result's recieved in the last hour, Result turn around time & Result creation rate graphs are updating. Just had a look at the Server Status page & it's been 37 hours since the other stats were updated.

I reverse my stand on this issue... I liked it it better when the RTS was flat but at half a million. I hereby request you break it again. (just no pleasing some people, is there?) :)
