Atlas internal server error
Probably it has been noticed but in case not I do report it, right now using Atlas we get :
[17:34:37,741] GET https://onionoo.torproject.org/summary/search/126.96.36.199 [HTTP/1.1 500 Internal Server Error 406ms]
Backend error! The backend server replied with an error to your query. This probably means that you did not properly format your query. If your query was properly formatted it may mean that there is an issue with your browser/add-ons. Please report which browser/addons/etc. you're using to the bug tracker.
