Ironically this page doesn't load for me
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.
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.
I go here :-)
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? :/

Can confirm for a number of sites, even Hacker News was unreachable for me.
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.
Based on twitter, the outage was on multiple continents. What would cause that? Subsea cable broken?
I'm in Hungary EU. My fiber works fine but 4G gone except for domestic addresses can't connect to anything
It wasn't a total outage for the site I was trying to reach. It took about 20 minutes to make an order, but after multiple retries (errors were reported as a 522 with the problem being somewhere between Manchester, UK and the host), it did go through.
I'm having lots of issues with Hetzner machines not being available (and even the hetzner.com website). Don't know if this is related.
Fyi I'm not having any problems right now with hetzner.com nor hetzner.de - my own dedicated server hosted at Hetzner datacenter in Germany seems to be reachable/working as well.

Connecting from Switzerland.

I am having trouble with Hulu right now. I bet it is related.
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.
Seconding this. Had some ssh connections timing out repeatedly just a bit ago. Also got disconnected on IRC.
Me too. I can only connect to one of my DO servers. The rest are all unreachable.
IKEA had their payment system go down worldwide also. I really doubt that uses Cloudflare.
It's not a just CloudFlare outage, its a global CenturyLink/Level3 outage
Is there a ranking board for which carriers have caused the most accumulated network carnage out there? I think the world deserves this.
As noticed in another comment I see loads of problems within Cogentco, all on *.atlas.cogentco.com. Might the problem lies there?
Cogent and Cox are also having problems, but we are seeing a lot more successful traffic on Cogent than CenturyLink. It appears that CL is also not withdrawing stale routes. It seems CLs issues are causing issues on/with everything connected to it.
I had problems accessing my Hetzner VPS', but I haven't tried connecting directly with the IP. So I suppose it could be a DNS thing?
Yup, definitely noticed earlier outages to both EU sites and also to HN. Looked far upstream because many sites/lots of things worked fine. Good to see it's at least largely fixed
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.
DDG, down detector are all very slow. Both are on cloudflare.

Fastly, HN, Reddit too.

Only Google domains are loading here.

From where I am (mid-altantic US) Google site are completely down (google.com, youtube)
M5 Hosting here, where this site is hosted. We just shut down 2 sessions with Level3/CenturyLink because the sessions were flapping and we were not getting complete full route table from either session. There are definitely other issues going on on the Internet right now.
Oooh, maybe that's why HN wasn't working for me a little while ago (from AU)...
Everything to Oracle Cloud's Ashburn US-East location is down.

Their console isn't responding at all and all my servers are unreachable. Their status console reports all normal though.

There is a major internet outage going on. I am using Scaleway they are also affected. According to Twitter, Vodafone, CityLink and many more are also affected.
Incidentally I can't connect to HN directly from Greece, but only if I use my VPN through New York. Probably somehow related?
Shameless plug:

I spent too much time losing precious time when github/npm/cloudflare are going down, until I figure out it was them.

So currently working on a project[1] to monitor all the 3rd party stack you use for your services. Hit me up if you want, access I'll give free access for a year+ to some folks to get feedbacks.

[1] https://monitory.io

FYI: Your site is down because of GitHub pages maintenance.

Edit: it’s up again!

Just want to let you know about the spelling error ”Save titme” :)

Maybe fix this typo? "Save titme on issues investigation"
And > Monitor all 3rd parties services

*3rd party services or possibly 3rd parties' services

Thank you, fixed it, I definitely didn't pay attention on this

Now wondering if it impacted conversion rate?

Your landing page doesn't build enough trust. You have run on sentences. It's still unclear what the service does.
Another typo:

> Know when services you depend on goes down

"Services go down", not "goes".

Hi Eric,

Congratulations on your startup!

There is at least one big tool that does exactly the same you wrote. It is called StatusGator https://statusgator.com There are at least 3 much smaller ones.

Have you tried any of them? If yes, what's your point of difference?

And how do you plan to market it? As I see the plans are cheap, means your LTV is low.

SalesForce/Office365 is also having trouble.
Odd, I'm trying to reach a host in Germany (AS34432) from Sweden but get rerouted Stockholm-Hamburg-Amsterdam-London-Paris-London-Atlanta-São Paulo after which the packets disappear down a black hole. All routing problems occur within Cogentco.

What seems to have happened is that Centurylinks internal routing has collapsed in some way. But they're still announcing all routes and they don't stop announcing routes when other ISPs tag their routes not to be exported by Centurylink.

So as other providers shut down their links to Centurylink to save themselves the outgoing packets towards centurylink travel to some part of the world where links are not shut down yet.

I just experienced HN down for several minutes before it loaded and I saw this story at the top.

I'm doing something with the HN API as I type this, so for a moment I was trying to decide if I'd been IP blocked, even though the API is hosted by Firebase.

I haven't noticed any obvious issues elsewhere yet.

(Just got a delay while trying to submit this comment.)

Half of the internet is down. Crazy...

I can't even access the private WoW server I play.

FWIW, I can’t connect to Madden NFL online servers.
Deployment to Netlify fails on installing of any version of Node :)
more specifically, npmjs.com and nodejs.org are not available from Netlify's datacenter due to this outage.
I have two pipes from two different (consumer ISPs) at home. One can reach HN, the other can't.

Incidentally, uBlock Origin seems to be completely broken. It doesn't have any local blacklists to work when their ?servers? are unavailable?

Looks like an issue with AS3356, they are advertising stale routes - lots of unrelated services impacted
