The status page first reported that CoCounsel was unavailable, then said at 20:48 that login access had returned while workspaces and files in the new CoCounsel experience in the US were still affected, until it marked the incident resolved at 21:25. Musixmatch and Amplitude also reported problems around the same time, and this was the second Thomson Reuters Legal outage in three days.
