The main issues with the improper functioning of the instance have been resolved, but it led to additional complications. Currently, using the instance should be quite comfortable, but I will continue to work intensively on a comprehensive solution for the next few days. Therefore, occasional interruptions or errors may still occur.
Thanks for your patience!
I’m the admin of mas.to. We didn’t block in the moderation sense (suspend/limit), we just stopped delivery of content to kbin.social to prevent even more failures and retries piling up. It wasn’t good for performance and probably not helping kbin.social either! I’ll start delivery again on mas.to and my other instance!
