Hey, don't know if you're mixing something up, feel free to correct me, but as far as I know, Nord never leaked user info. Wasn't it a server breach, that didn't really yield any results for the hackers?
Also, yeah, if you go on PIA's reddit people are freaking out about all kind's of instabilities. I think it all started with them rolling out their next gen servers, maybe things will stabilize, but obviously you want to use the service now and not wait for a month.
