Update: The migration went as planned, and we finished early. We may experience momentary server hiccups as we adjust the memory usage according to the server load.
We will be relocating the Movable Type blog installation to a brand new server location and moving the database to an external MySQL Enterprise server the morning of Tuesday, July 13.
This will require a scheduled outage between 8 AM and 11 AM on Tuesday. We will try to maintain website access during most of that time. However, the need to place a freeze on file and database changes will require that we disable the admin interface.
If all goes as planned, the entire three hours will not be necessary.
