The site started having trouble keeping up with requests starting some time yesterday. I implemented some quick fixes but the rate of requests was still too high for the small VM TreeStats.net runs on over on DigitalOcean. I bumped the RAM up to 3GB today after continued instability and downtime earlier today and things seem to be back in operation. Please get in touch in Discord if you see anything not working normally or want to contribute anything to the $15/mo hosting plan TreeStats.net runs on.
