I'm having issues reaching IP addresses unrelated to Cloudflare. Based on some traceroutes, it seems AS174 (Cogent) and AS3356 (Level 3) are experiencing major outages.

View on HN

Is there any one place that would be a good first place to go to check on outages like this?

It would be really cool and useful to have an "public Internet health monitoring center"... this could be a foundation that gets some financing from industry that maintains a global internet health monitoring infrastructure and a central site at which all the major players announce outages. It would be pretty cheap and have a high return on investment for everybody involved.

Until that site also goes down.

Indeed, if we're to have a public Internet health meter, it must be distributed and hosted/served from "outside" somehow, to be resilient to all or parts of the network being down.

Here's a thought: we should all be outside. :D

Something something anycast.

Sounds like a good idea. The closest i know is the one from pingdom which i use the most. Its not detailed enough though. https://livemap.pingdom.com/

In the network world there's the outages mailing list:

Based on that map, Telia seems to be one of the most affected which might explain why Scandinavia is so badly affected.

You just imagined the first target in an attack. Might as well just call it honeypotnumber1.

This is an excellent idea and simple but moderately expensive for anyone to set up.

Just have a site fetch resources from every single hosting provider everywhere. A 1x1 image would be enough, but 1K/100K/1M sized files might also be useful (they could also be crafted images)

The first step would be making the HTML page itself redundant. Strict round robin DNS might work well for that.

But yeah, moderately expensive - and... thinking about it... it'll honestly come in handy once every ten years? :/

Reddit, HN, etc. are inaccessible to me over my Spectrum fiber connection, but working on AT&T 4G. It’s not DNS, so a tier 1 ISP routing issue seems to be the most likely cause.

Lots of local sites not working in Scandinavia either. So seems more global than a single Tier 1?

Probably relevant Fastly update:

> Fastly is observing increased errors and latency across multiple regions due to a common IP transit provider experiencing a widespread event. Fastly is actively working on re-routing traffic in affected regions.

HN and reddit out on my talktalk link in London, 3 mobile 4g working normally.

Can confirm for a number of sites, even Hacker News was unreachable for me.
