Wrong domain/server configuration?
purelink.kd.io might be pointing to an nonexistent server. You can correct this by logging in and checking your "Environment Settings". Make sure this domain name is pointing to a server that's healthy and serving a web site. (e.g. if you stop your webserver, or run it on a different port that we don't know about, this error can happen.)
Our servers are not doing okay
If this is your server and you've done everything right, it's probably our fault. Please let us know at support@koding.com
