Bluesky is growing quickly in popularity, but if you’re trying to use it today, the site might be acting up. As I was writing this article, my feeds and notifications were very slow to load on the web and mobile while logged in, and that has similarly been the case for a few of my Verge colleagues.

Things seem to be working now, but Bluesky developers have already warned that things might not work as expected today. Earlier this morning, developer Samuel Newman shared that the site would be briefly going into read-only mode because “something fell over.” After the site recovered, another developer, Paul Frazee, posted that “today will get interesting” and suggested that if the site goes down to “maybe grab a soda, pet the kitty.”

When there’s an outage, Frazee says you might see things like an “Invalid Handle” message, likes not seeming to work, or “random errors or blank screens.”

Bluesky didn’t immediately reply to a request for comment. The platform crossed the 15 million user mark yesterday, and the Bluesky app is currently the top free app in the App Store. Threads, however, is still much larger, having more than 15 million signups already this month.
