Apparently the site about Static Site Generators is experiencing application problems and is unable to serve content at the moment. Should I be amused or enraged?
The downtime was caused by the YAML file having invalid syntax so it would not parse. Whenever a modification to the YAML file is made, a github post hook is sent to the server telling it to regenerate the website.
Normally this happens smoothly without anyone noticing any downtime, while maintaing awesome performance.
In this case because of the bad YAML, DocPad crashed, as it was told to, and the logs showed the error.
I was sleeping at the time so did not notice the issue.
The latest version of the website now handles this gracefully, using the latest successful data if the YAML is bad, as well as showing an error message.
