Right after chacha came online there were 1000+ concurrent users. Then it turned out it was actually the open tabs a user had open in their browser irrc. After an update I saw 700-800 on the regular which unfortunately kept dropping to now ~500 (at the beginning we had a lot of struggle sessions which might ve been the cause). Also during election night I saw the number pick up to 1000. Maybe the dev team can share factual/non annectdotal stats
