Some LHCB specific SAM CE tests were systematically failing everywhere because of a bug in one of the modules for installing software. These tests have been temporary set "not critical" until a fix will be in place and fully tested.
However for once Glasgow knew about these failures at 23:45 last night - The WLCG monitoring plugin did exactly what it should, picked up the SAM failure on its poll of the test results and notified glasgow by email.
The latest (SVN) version of the ncg.pl script has support for multisite configuration by the inclusion of
<NCG::SiteSet>sections in the config. Not tested it yet - thats on the rest of the weeks TODO list
