I've been getting similar issues. Wired network, on PC. No congestion (i'm only user, happens even very late at night, during weekdays, evenings, doesn't matter). Using Comcast in the greater Seattle suburbs Immediately after the patch last Tuesday, sudden uptick in infinite loading screens, being kicked out of activities with network errors, with no apparent cause. In strikes, in patrol zones, in pvp/gambit, doesn't matter. Many people in my discord who were not having issues have seen a sudden increase in similar issues, and it's not happening just during Bungie's frequent maintenance windows this week. While it's possible it's my end, there's far too many coincidences pointing to something specific that changed to kick this off.
