XBox NA.
Since last week's emergency maintenance, about 10-20% of the time I switch between zones / encounter a loading screen, it turns into an unusually long load time, then disconnects me. I have a Series X, so unusually long load times are rare, and this uptick definitely unusual for me.
Did my first bit of group content since the maintenance this evening, and it was happening to others in my group as well. When someone was impacted, it didn't show them grayed out like someone in group who logged out, it showed an empty space. The group roster didn't reform like we were 11 people. The roster just had a hole in it.
