I think I know the answer to this but...
I was just poking around in some Steam community pages and I found the Bad Cartridge/D1P group (anyone not in it already should join!) and I noticed that its description mentions the TF2 server. Unfortunately, I can't even remember the last time I played on it (maybe 2015 ? ) and when I tried to connect to the IP given in the Steam group from within TF2, it said it couldn't find anything. It's gone, right @Commissar SFLUFAN ?
Would people still potentially be interested in a TF2 night some weekend, for old time's sake?
