Since this morning I noticed a few 1000 requests to ccfrontier.in2p3.fr which usually only occurs if something is wrong with lcgft-atlas.gridpp.rl.ac.uk.

There is a problem with that server caused by overloading in the last few days (not from LHC@Home but other tasks). Experts are investigating. But in the meantime the failover should work ok.

Yeah, not so much. I've had to abort several work unit transfers as they just keep slowing down till they stop and have to be repeatedly restarted. When it happens BOIINC blocks the project and won't attempt any more transfers or request any more work until the download completes.

What does "work unit transfers" mean for you?
Download of EVNT files or upload of HITS files?
Those transfers never go via lcgft-atlas.gridpp.rl.ac.uk or ccfrontier.in2p3.fr.

As long as your firewall allows outgoing traffic to destination ports TCP 3128 (-> lcgft) and TCP 23128 (-> ccfrontier) you should not see any differences in speed.

Your problems might have another reason.
Further help is not possible as long as your computers are hidden.

That thing where work units are transfered from the CERN servers to the client computers. In the BOINC client they show up under the "transfers" tab. I specifically mentioned downloads. I have no firewall restrictions at this time.

I currently have two Atlas VM units that have been progressing extremely slowly for the last two days. Since they immediately stop when I suspend networking in the client, and given the repeated download failures of other work units I am suspicious of the project servers.

I have had no trouble with any other project I have tried.

The tone of your reply indicates you have no intention of helping, so I am just going to abort them and let someone else deal with you in the future.

This is the reason why you don't see any progress.
LHC VMs need permanent network access.


The tone of your reply ...

.. is always friendly as long as your's is friendly.

Agreed.
