We're suffering from information system dropouts. This seems to happen particularly when jobs come into the site - I can see that the load on the CE jumped to about 10 as the number of jobs ramped up last night. The corresponds exactly to the time that we start to drop out of the BDII.

So it's really urgent that we have a separate site BDII to stop this happening (we failed a few SFTs because of this).

It is a pretty poor show from the BDII to be so sensitive about the CE's load.
