The following issues have been affecting myself and by word of mouth some other players in Halo Reach.
Matchmaking hangup during the “Acquiring Data” portion of loading the maps. Results in having to quit game outright.
No population counter
Upstream bandwidth at warning level despite Xbox one and PC software testing coming back fine.
Random but definitely much more than usual corrupted recent films data.
These are not local to just myself there are definitely other players experiencing the same issues all starting sometime around August 1st.
