As of a few days ago, this site has been taken down by the Replit moderation team, likely for going over the bandwidth limit, or because Replit haven't removed the ability to uptime repls, they never said they wouldn't remove uptimers.
I appoligise deeply for this, but the service is going to end here. In future, I hope to re-open the site, but it's uncertain if this will be possible, as replit may view it as DoS later on, and it costs far greater to host elsewhere.
