kind of confused over what’s happening with the internet over here. i thought rebooting the broadband routers supplied by the ISP (configured in bridge mode) had resolved the internet connectivity issues, but it seems it’s just going up and down randomly. i suspect it’s the isp that has trouble... or, for all i know, some dude is up a pole down the street, rewiring things. it was doing this earlier too, right before it went down completely.

@thor You having internet issues? I had from about 12:15 until 30 minutes ago when I found out switching from OpenDNS fixed it.

@thor Not sure if it really was OpenDNS' fault, but both my Pi-holes started failing at once which was a huge hint. Turns out that switching them from OpenDNS to any other DNS provider fixed my internet

@thor Yeah you don't have the same issue as me, I was just curious if OpenDNS was having issues in Norway if others had the same issue as me.Also those ping times, even DSL tends to be better than that, is your connection always that bad?

@thor I thought 8.8.8.8 was pretty much plugged into NIX?I always get near identical ping times to nix.no and 8.8.8.8 at least. But I don't know any test ip to NIX besides their website, their route servers don't seem to respond to pings at all.Currently I have 19.5ms to nix.no and 20.5ms to 8.8.8.8

@thor when stuff like this happens it usually means there was a routing fuckup somewhere in their network, not that equipment failed.Who knows, maybe a bunch of their shit somehow failed if they're having openDNS issues like me.Doubt it though, and ISPs internal operations hopefully don't rely on openDNS

@quad is the address 8.8.8.8 routed differently depending on the country? i mean i guess it makes sense. but yeah, ping times to nix are usually very low. i haven’t tested them right now. more concerned with internet access itself than ping times. when the internet came up again earlier, vg.no loaded instantly.

@thor Well yes, 8.8.8.8 uses anycast. There's servers all around the world and you hit the one closest to you.Since I've always had about identical ping times to both nix.no and 8.8.8.8 I always just assumed there was an 8.8.8.8 server pretty close to NIX

@thor P.S just noticed cloudflare is reporting issues with a transit provider: https://www.cloudflarestatus.com/Around 10:20 UTC. Which is 12:20 in Norway. Coincidentally 5 minutes after I started having issues.There's probably one big ISP somewhere fucking up everything and might be why Lyse are having issues too. And why my OpenDNS stopped working

@thor @quad Everywhere-- it's a Tier-1. Most networks use it, directly or indirectly. Also since it's being down, lesser-used links are now used, which tends to saturate, etc.

@thor @href Level3 probably won't affect 8.8.8.8 at nix.But it's very plausaible that Level3 goes down, something at your ISP goes "Oh no!" because it doesn't handle it and crashes, then you lose internet.Although to my knowledge level3 doesn't operate much in Norway (if at all outside of NIX?) so it shouldn't have much of a direct effect on us. But the internet is more fragile than you think. A single Trier 1 ISP fucks up and the dominio effect will kill far more of the internet than it should

@quad @thor According to bgp.he most of the routes of Lyse goes thru Level3. So it definitely should have saturated some links and stuff at Lyse, or at NIX, or both. And I agree, 8888 shouldn't pass by Level3 nor Telia for Lyse (since google is at NIX) and Lyse too).

@quad @thor Also since Level3 wasn't respecting route withdrawals, as most ISP tried to shut down their links with Level3, that was resulting in blackholes... that aggravated the situation as well.

@thor @quad yeah, 8.8.8.8 is anycast, so that usually means that your ISP will choose the shortest route. Maybe NIX has issues, or your ISP link to NIX, or Google link to NIX. Routing is weird, especially is that time where Level3 is shitting around.Lyse seems to have peering at NIX.
