So, that's why HN is unreachable from Belgium at the moment (right when I was trying to figure a dns cache problem in Firefox,of course). An ssh tunnel through OVH/gravelines is working so far. edit: Proximus. edit2: also, Orange Mobile

HN working for me from the UK on BT, but traceroute showing lots of different bouncing around and a lot of different hops in the US 7 166-49-209-132.gia.bt.net (166.49.209.132) 9.877 ms 8.929 ms 166-49-209-131.gia.bt.net (166.49.209.131) 8.975 ms 8 166-49-209-131.gia.bt.net (166.49.209.131) 8.645 ms 10.323 ms 10.434 ms 9 be12497.ccr41.par01.atlas.cogentco.com (154.54.56.130) 95.018 ms be3487.ccr41.lon13.atlas.cogentc…

Guessing the traceroute looks a bit messy because of multiple paths being available.

You can use `-q 1` to send a single traceroute probe/query instead of the default 3, it might make your traceroute look a little cleaner.

I had to use a VPN With US location to post this comment. I am in Europe.

Works OK in Paris via SFR (home fiber) and Sipartech (Business fiber).

Doesn't work via Bouygues 4G.

My SFR fiber doesn't seem affected all that much. I've been following this for a while on the other HN post [0] and all services people have noted seem to work here.

Both SFR and Sipartech seem to have direct peerings with Cogentco.

edit: Spotify seems partially down: app doesn't say it's offline, but songs won't play.

This explains a lot. Initially thought my mobile phone Internet connectivity was flakey because I couldn't access HN here in Australia, whilst it's fine over wi-fi (wired Internet).

Its reverse for me. The broadband fails to connect to HN but my mobile ISP is able to reach it fine.

I hope these kind of “ipv4” only outages encourages more and more websites to upgrade to ipv6. #OutageBenefit ;)

It would appear from the limited info so far, to be an issue in the v4 routing configuration - I haven’t seen anything that says this couldn’t have been the other way around.

Looks like Centurylink/Level3 (as3356) might not be withdrawing routes after people close their peering?

What could cause this? I wonder what the technical problem is.

We had this once with one of our former ISPs configuring static routes towards us and announcing them to a couple of IXPs. I have no idea why they did it, but it caused a major downtime once for us and basically signed the termination.

Because networks are connected to others via different paths, it's not unusual that one method of connectivity would work and one doesn't.

Also the Internet has lots of asymmetric traffic, just because a forward path towards a destination may look the same from different networks, it doesn't mean the reverse path will be similar.
