This morning (March 20th) our hosting provider required to move some of our servers to new hardware, as a normal, preventive move. This can have caused some of our scripts to respond slowly, or not at all in some cases. But the failures were very few, and very short lived. All our systems are now back to normal. We apologize for the trouble, an unfortunate but unavoidable situation on 24/7 systems like ours. We have kept failures to the very minimum, and will do so on any future such incidents. Thank you.
