Update (July 8): We're still working on it. Online counts will be available soon™
Due to persistent issues scaling the bot for online counts, we're disabling this feature until we've rewritten it to perform in a more consistent and reliable way.
This also results in the bot appearing offline. Don't worry, people can still join servers like normal. The bot does not rely on being online to create invites.
We don't have a hard estimate, though we expect the feature to be available in about a week.
