Recent Downtime

The recent downtime was caused by an issue with one of our hosts which has been resolved.

Due to security measures in place, some work had to be done to get everything back up before we were able to get the site online. We're always going to prioritize user security, before all else and we're sure you all agree, keeping your data safe is more important than having slightly better availability.

Our sincerest apologies for the massive inconvenience.

PS. Fun news coming up within a few days!
