Discord is having issues too!

Facebook + Insta makes up a huge share of the social media market, and when they go offline, it'd be natural for their competitors to receive large sudden upticks in trafic they're not immediately prepared for on a Tuesday morning.
That rollout is staggered over time, so not all users receive it at the same time. It's unlikely to be related.
Which, I guess, is the best possible redesign: one that freshens up without rocking the boat.
