I am a developer on
https://github.com/new-xkit/XKit
(New XKit), an extension framework for additional tools and changes on Tumblr.Our updates happen via our github.io domain, where JSONs are hosted that the extension pings every so often in order to update the relevant extension. However, due to a recently added (seemingly temporary) block on github.io via third party websockets and XmlHttpRequests, this update procedure is broken for many users, and get the message they cannot connect to our servers.
I would like to kindly request you either ALSO allow tumblr.com in addition to github.com, or in some way create an exception for
http(s)://new-xkit.github.io/XKit
and its subdirectories.
