Rackspace downtime

We've had two network outages over the past month at Rackspace.

The first was a black swan event. A core router went down, and their
backup to that core router failed to take over correctly. The site was
down for around 2 hours while they fixed the router.

The second was scheduled maintenance earlier this morning. The site was
down for 1 hour.

These are the only two outages that we've had, and they're the worst
outages that we've ever experienced at Rackspace. We've had at least one
complaint about the repeated downtime.

There has been some chatter on the #json-ld channel about using Google's
caching CDN as a backup in these cases. This would have two positive
effects. The first is that files would be cached and served faster
around the world. The second is that if there is a failure for the
w3id.org website (like the one's we've had over the past month), the CDN
will serve the files until the website comes back up.

A potential downside is that if the CDN goes down, we have the same sort
of issue as we have right now. However, Google's CDN has been
notorious for having true 100% uptime.

Just throwing this out there as something we're thinking about. No solid
plans to use a CDN yet.
