XKit fails to update: What’s going on?
Short answer: Everything is completely fine. All extensions are intact and the problem should fix itself soon.
Long story: Unfortunately, Github is affected by a massive DDoS attack right now and connections to it are intermittently failing. Since we use Github to host our update data and XKit may not be able to connect to it, this could temporarily affect the ability to download new extensions from the gallery or update existing ones. As soon as the DDoS attack stops and Github resumes its normal operation, XKit will work as usual once more.
As always, our inbox and chat room are open for those with support issues. Thanks!
