Hey, if you've used the site between 1 am and 2 am today (2024-02-01), then you might have noticed that it was down for an hour. This was due to a known corruption issue in the database that we don't exactly know where it comes from. We're still investigating. It took us a while to find a solution because corrupted databases are always really scary, and mistakes can be consequential. But by rolling back the trie's root to the prior root, we managed to recover all messages, and the site is now back up. This is very good because today was an all-time high in DAU, and it would have been so bad if that data on the achievement was now lost!
