Hi,
Liverpool have failed a number of SAM tests over the last day or so,
which seem to have all resulted from missing entries in BDII or being
unable to connect to lcg-bdii.gridpp.ac.uk.
Other sites have had a number of failed tests over the same period.
We've also seen a number of temporary blips in our SAM tests over the
past few weeks, resulting from a lack of entries for our SE in BDII.
We've been unsure if this is anything to do with our glite 3.2 BDII or a
flaky VM system.
As some of the recent tests have included lack of entries for external
systems as well I'm wondering if the GridPP BDII server is experiencing
problems for other sites as well and if other Tier2 sites without
problems are using a different top BDII.
Should we all be using the same BDII or is there something to be gained
from a *coordinated* distribution of external services to mitigate the
otherwise single point of failure that BDIIs can represent within the UK
cloud?
John
