The JIS database of clubs was already out of date and not responding to update requests ~25 years ago. For an actively-maintained list of events and clubs there is: https://www.jugglingedge.com/ -- which is where most of the rec.juggling and IJDb community went when IJDb shut down. There are probably more active forums now, but it's still the cleanest and most comprehensive list of juggling clubs and events that I know of.
