Fix rubygems.org status check

[evanphx]

statuspage.io changed their CSS, so this needs to change too!

[TildeWill]

What about monitoring some part of the status site that isn't DOM/CSS dependent? Suggesting the RSS feed: https://status.rubygems.org/history.rss

[andistuder]

AFAIK histroy.rss feed does not have the required data to evaluate the current status. Better would to to query https://status.github.com/api/status.json - this will return something like

{"status":"good","last_updated":"2016-02-05T09:12:28Z"}

see docs: https://status.github.com/api

I don't see why the status of github is relevant to this issue. Is there such a json query for rubygems, too?

[andistuder]

@Khoulaiz 😊 I mixed something up here, thanks for spotting. But luckily, Rubygems offers a similar service: https://status.rubygems.org/api#status
