Unix may be shut down for maintenance for a while during the morning of next Tuesday (the 24th). Such shutdowns usually last only an hour or so but that cannot be absolutely guaranteed. The most likely time is about 0900.

There is some possibility that there might be a service interruption for disk maintenance on Tuesday (21st) morning. Such interruptions normally don't last longer than about an hour, and normally begin about 0900. If it's not this week then it will be next week. (Theoretically it ought to be next week, but the maintenance people are sometimes a bit inconsistent about their schedule.)
