Earlier I mentioned that the FAQ site might be down for a day or two soon. I have just received a more specific notice from the host, and part of it is quoted below.
"We've been very diligent in planning the move of our data center and we're on schedule with all preparations. Our primary target date for the relocation of all servers is the end of next week: Midnight, Friday March 28th. At that time, for a period of up to 48 hours, there will be service unavailability. It is not certain when your account will become unavailable or how fast it will come back up. Please allow ample time for us to make the move safely and securely."
The time base is US EDT, so the site might go down before midnight for those in Europe.
If the situation changes, I will post again.
