I've been using JSBin for my highschool courses for some time now. Recently I had a problem where my class couldn't access JSBin anymore halfway during the lesson. JSBin remained blocked for a few hours, and then became accessible again. I'm wondering if JSBin has some automatic DoS protection that kicks in when joining a bin and updating it a lot with about 30 students, all at once. I've seen this in two separate occasions.\r\n\r\nOn monday 14 september, 29 students joined the bin at http://jsbin.com/vopoquroyo/1/edit?js,output and started editting. In about 5 to 10 minutes, JSBin became inaccessible on all computers, with a 'cannot connect to server' error. It seemed that the browser couldn't successfully complete a TCP handshake. Using a different network/IP address showed to me that JSBin was working fine for the rest of the world.\r\n\r\nOn both tuesday 15 september, 31 students joined the bin at http://jsbin.com/jafubutici/3/edit?js,output and were blocked in less than 10 minutes. Same story as with monday.\r\n\r\nIf there is any automatic blocking, would it be possible to whitelist the school IP address? I unfortunately haven't recorded the IP address, and can't look it up until monday.\r\n\r\nThanks a lot for making JSBin possible, it's really a great educational tool!"},"comment":{"url":"https://api.github.com/repos/jsbin/jsbin/issues/comments/151276945","html_url":"https://github.com/jsbin/jsbin/issues/2552#issuecomment-151276945","issue_url":"https://api.github.com/repos/jsbin/jsbin/issues/2552","id":151276945,"user":{"login":"jonjohnjohnson","id":181364,"avatar_url":"https://avatars.githubusercontent.com/u/181364?v=3","gravatar_id":"","url":"https://api.github.com/users/jonjohnjohnson","html_url":"https://github.com/jonjohnjohnson","followers_url":"https://api.github.com/users/jonjohnjohnson/followers","following_url":"https://api.github.com/users/jonjohnjohnson/following{/other_user}","gists_url":"https://api.github.com/users/jonjohnjohnson/gists{/gist_id}","starred_url":"https://api.github.com/users/jonjohnjohnson/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jonjohnjohnson/subscriptions","organizations_url":"https://api.github.com/users/jonjohnjohnson/orgs","repos_url":"https://api.github.com/users/jonjohnjohnson/repos","events_url":"https://api.github.com/users/jonjohnjohnson/events{/privacy}","received_events_url":"https://api.github.com/users/jonjohnjohnson/received_events","type":"User","site_admin":false},"created_at":"2015-10-26T20:36:35Z","updated_at":"2015-10-26T20:36:35Z","body":"Pretty sure this is happening to me currently.
