The article states internet was down for users at around 10pm (I expirenced it live). So they might have been on generators for two hours (speculation).
Largely agreed with you, though as general advice I would say that redundancy by adding more exchanges to your network serves you better than adding diverse connections to a single exchange.
Yep, that makes a lot of sense, especially since 10G/100G waves and such on the FLAP route are so inexpensive. Getting a remote peering port on AMS-IX or something is probably a good move.

In fact, we're hit by this again, down again at 22:09:19 EST for me and still down. Their website is broken too (https://www.de-cix.net/) and their email servers are offline which makes contacting them amusing.
Not much to be done, really, fortunately the impact for us is very trivial.
General home connectivity also suffered, at least a few people (and myself) had connectivity issues, if you search for @vodafone_de on twitter you'll see a lot of people complaining (though I assume it was not just vodafone with issues)
Keep in mind this is only one of the many DE-CIX datacenters, they exist in at least 8 datacenters in Frankfurt: https://twitter.com/goebelmeier/status/983453047543214081
Only those peers who are single-homed to Interxion FRA5 / DE-CIX6 will have experienced an outage.
