This has been discussed over the last few days amongst the ATMs and DATMs.
The VATUSA standard will continue, as the rest of VATSIM, to provide Local control services where Local control services are provided in the real world. That means that if these facilities close, whether it be for an hour, a day, a week, a month, or forever, we will mirror what the real world does.
I do, however, for a yet-undetermined transition time (thought to be a small number of weeks), support the notion that has been proposed by a few of the ATMs, to allow Local services to be provided on an as-requested basis, if requested by a specific pilot, on a case-by-case basis where the controller feels that workload allows. Please be very clear: this will be allowed for a very short transition time solely to allow for a buffer to allow our ATC and pilots to adapt to the change.
Folks, politics has no place on VATSIM. I don't like any facility closing, and this forum is no place to debate whether or not those decisions are "good" or not. But, VATSIM is about providing our members a simulation based on reality. The current reality changes on occasion. We, as our RW counterparts, will deal with that, the best that we can recognizing that this is still meant to be a fun hobby (not saying chasing hourly or daily NOTAMs), and do the best that we can for our members.
As was mentioned, I suspect that most of these facilities don't get a ton of traffic on VATSIM while controllers are online, so I suspect that this is not a huge game changer for us. Let's not turn it into a major issue with pages and pages of discussion. In our environment on VATSIM, it's not worth it. I encourage you to channel your passion into improving the experience for our members.
