Announced through a Facebook and a VATSIM forums post, Matthew Cianfarani, the VP for Network Infrastructure of the VATSIM network, has indicated that VATSIM was starting a migration of “most of [their] websystems onto a new infrastructure”.
The time window for the migration is set from Monday, March 2nd @1700Z through Wednesday March 4th @1700Z.
Some services will be disabled and databases won’t be written during the migration. Servies such as new user registrations are temporarily unavailable, as well as several servers such as the stats server and the main vatsim.net domain.
The status of the network servers can be accessed at all time through this website.
