I think the suggestion is they're basically being Slashdotted. The platform seems to have issues particularly when a subcommunity suddenly becomes very active.

I think the suggestion is they're basically being Slashdotted. The platform seems to have issues particularly when a subcommunity suddenly becomes very active. Reddit is a very popular site, but is not usually subject to big spikey influxes of new visitors, just the regulars. So when a subreddit gets in the news big time (like with WallStreetBets) the site tends to crash.
