How is data transmitted from stations?

I’m just curious about something. Do the Weatherbug stations that are located at schools use the school computers/server to transmit data?

The particular station/school I usually select has been unavailable for the last week or two. I heard from a school employee (who heard from the tech guy) that a virus was in the server and infected all the computers and backup tapes. They said this happened within the past two weeks.

So that made me wonder if that’s why that station has been unavailable. Otherwise I guess it’s just a coincidence.
