It is extensive and up to date but it is lacking a brief status of the current situation and whether the site is safe to download from. The answer is currently "no", 90% safe is unsafe. It's a shame that they seem to have put the service back up in an unsafe mode, I would have hoped that they could have quarantined the unverified Gems. Edit: Looking at the status page the API is down so it can't be accessed from Bundler so they are doing it the good/safe way.
