Before: not present
After: The success rate for Mastodon publishing over the past hour has significantly increased, and although both mastodon.social: http://mastodon.social and mastodon.online: http://mastodon.online status pages still show “investigating”, the behaviour we’re seeing suggests the issue may be resolved. We'll continue to monitor this.
Before: not present
After: The issue with Mastodon has been resolved, and their servers are performing normally. If you have experienced failed posts during this time, please click Retry Now on each one to try publishing them again.
