We've been having an issue for some time now, that all our Grid is up, but the beacons say offline for most or all of the sims.

We don't use the Dreamgrid 'pause', and every time I check, the sim is up and well. I do resets of the sims when I notice, which does get the beacon to work again - but be aware that most of the time, a particular sim is likely really available and running :)

Just paste in the SURL and give it a try!
