I don't want to have to create a bunch of GGUS tickets. The following sites have yet to update their squid monitoring so it works with the new machine (http://wlcg-squid-monitor.cern.ch/):
UKI-LT2-RHUL <-- Govind already contacted me.
I note that all the CMS sites have updated!
If you have done it but it doesn't seem to have worked it may simply be a case of reloading the squid settings (which I missed out of the original instructions):
$ service frontier-squid reload
The instructions can be found:
Thank you in advance for your help.
