Oof, I was watching this thread and letting it go because I thought people knew.
It's a protest action, and not only 2K, but RDR2 and GTAO are down for a couple hours as well. Everything under the T2 blanket. It's not outwardly stated maintenance, although it wouldn't really surprise me if they used the downtime to do a little bit of back-end work.

In any event, it should be coming to an end in a few minutes.
