I had this earlier! A bunch of sites were down for me, I couldn't even connect to this site. The problem is I don't know where to find what was going on (tried looking up live DDOS-tracking websites, "is it down or is it just me" websites, etc. I couldn't find a single place talking about this. Is there a source where you can get instant information on Level3 / global DNS / major outages?

Ddos tracking sites are eye candy and garbage. Stop using them. Outages and nanog lists are your best bet, short of being on the right IRC channels.

What are the right IRC channels?

I agree!

I'm definitely an amateur when it comes to networking stuff. At the time, the _only_ issue I had was with all of my Digital Ocean droplets. It was confusing because I was able to get to them through my LTE connection and not able to through my home ISP. I opened a ticket with DO worried that it was my ISP blocking IP addresses suddenly. It turned out to be this outage, but it was very specific. Traceroute gave some clues, but again I'm amateur and I couldn't tell what was happening after a certain point.

So yeah, I too would love a really easy to use page that could show outages like this. It would be really great to be able to specify vendors used to really piece the puzzle together.

Judging by other comments, it seems there's a space to fill this niche with a series of blog articles or a book, if you're that sort of person.

There are plenty of presentations out there. See nanog, ripe. The books are meh because they're not written by operators. They're more academic and dated. Plenty of clueful folks on the right IRC channels.

Second time in this thread you've mentioned the right IRC channels. Does one need to invoke some secret code to find out what they are? :-)

Has anyone any good resources for learning more about the "internet-level" infrastructure affected today and how global networks are connected?

Read Internet Routing Architectures by Sam Halabi. It’s almost 20 years old now but BGP hasn’t changed and the book is still called The Bible by routing architects.

It's dated and not particularly useful if you want to learn how things are really done on the internet in a practical sense. So if you read it, be prepared to unlearn a bunch of stuff.

Misread the headline as "Level 3 Global Outrage" and thought "someone had defined outrage levels?" and "it doesn't matter, he'll just attribute it to the Deep State".

In some ways I'm a little bit disappointed it's only a glitch in the internet.

I was doing development work which uses a server I've got hosted on digital ocean. I started getting intermittent responses which I thought weird as I hadn't changed anything on the server. I spent a good ten minutes trying to debug the issue before searching for something on duckduckgo, which also didn't respond. Cloudfare shouldn't be involved at all with my little site, so I don't think it's limited to just them.

Same here. I actually opened a support ticket with them because I was worried my ISP had started blocking their IP addresses for some unknown reason. Luckily it seems to clear up, and in the ticket they mentioned routing traffic away from the problematic infrastructure. Seems to have worked for now for my things.

in certain instances, yes depending on the nature or subject matter of the channel

ok lets go for broke, there are a LOT of clandestine IRC servers and exclusive gatekeeping of channels. you wont know about unless you have an IRL reference

Were their tweets protected (i.e. only visible to approved followers) when you posted that link, or is that in response to this event?

Level3 was qquired/merged/changed to century link a year or so back, I think they closed their old twitter account then When someone says level3, read century link. L3 have been a major player for decades though (including providing the infamous 4.2.2.2 dns server), so people still refer to them as level3. The account to follow for them now is https://mobile.twitter.com/CenturyLink but it won’t tell you much.

Note that L3 is a separate company from Level 3 Communications, which was the ISP that was acquired by CenturyLink. L3 is an American aerospace and C4ISR contractor.

CenturyLink's current CEO, Jeff Storey, was actually the pre-acquisition Level 3 CEO.
