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 don't normally see multi paths for a given IP, but that aside it's bouncing through far more than I'd expect. That said, it's rare I look at traceroutes across the continental U.S, maybe that many layer 3 hops are normal, maybe routes change constantly. HN has dropped off completely from work - I see the route advertised from Level 3 (3356 21581 21581) and from Telia and onto Cogent (1299 174 21581 21581). Telia is…

This is normal for Cogent. They do per-packet load balancing across ECMP links. What you're seeing is normal for the given configuration.

A RIPE ASN (as a end-user through a LIR) and PA v6 will cost you around $100 per year and some mild paperwork, there's plenty of companies/organizations that will help you with that (shameless plug: bgp.wtf, that's us). Afterwards, announcing this space is probably the cheapest with vultr (but their BGP connectivity to VMs is uh, erratic at times) or with ix-vm.cloud, or with packet.net (more expensive). You can also…

> bgp.wtf, that's us I feel like you ought to be part of the ffdn database: https://db.ffdn.org/ Though the "French Data Networks Federation" is a French organization, their db tries to cover every independent, nonprofit ISP in the world :)

That couldn't work, unfortunately, per https://www.ffdn.org/en/charter-good-practices-and-common-co... :

> All subscribers to Internet access provided by the provider must be members of the provider and must have the corresponding rights, including the right to vote, within reasonable time and procedure.

Not all of our subscribers are members of our association. The association is primarily a hackerspace with hackerspace members being members of the association. We just happen to also be an ISP selling services commercially (eg. to people colocating equipment with us, or buying FTTH connectivity in the building we're located in).

Build an industry coalition. Put pressure on those who don't join. Randomly throw away 1 out of 10000 packets from the providers that fail to get with the times. Increase that frequency according to some published time function.

Having a single, cryptographically assured source of truth for routing data is a turnkey censorship nightmare waiting to happen. All it takes is a national military to care enough to put pressure on the database operator, legal or otherwise, and suddenly your legitimate routes are no longer accepted. If you think this wouldn't be used to shut down things like future Snowden-style leaks or Wikileaks or The Shadow Brok…

sneak you should come back to irc :)

Unfortunately, this infrastructure is at an uncanny intersection of technology, business and politics. To learn the technical aspect of it, you can follow any network engineering certification materials or resources that delve into dynamic routing protocols, notably BGP. Inter-ISP networking is nothing but setting up BGP sessions and filters at the technical level. Why you set these up, and under what conditions is a…

What resources can I follow to start a non-profit ISP? I want to start one in my hometown for students who couldn't afford internet to join online classes.

Why not just raise money to pay for service from for-profit providers? Much more efficient use of donation funds.

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

It's important to recognize that there is a "layer 8" in Internet routing-- the political / business layer-- that's not necessarily expressed in technical discussion of protocols and practices. The BGP routing protocol is a place where you'll see "layer 8" decisions reflected very starkly in configuration. You may have networks that have working physical connectivity, but logically be unable to route traffic across each other because of business or political arrangements expressed in BGP configuration.

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?

https://mobile.twitter.com/Level3 (not an internet level, just a company :)

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.

There's a bunch of guidelines for starting a (W)ISP depending on your region.

I actually tried, but all I got was some consultancy services that would help you get an ISP with estimated cost of 10k USD (a middle class household earns half of that in a year here).

> A RIPE ASN (as a end-user through a LIR) and PA v6 will cost you around $100 per year ARIN starting price is 2.5x that much (used to be 5x) for just the ASN. Glad the pricing is better elsewhere in the world at least!

If you try to become an LIR in your own right, RIPE fees are much higher.

If you're looking for PI (provider independent) resources from RIPE, the costs to the LIR (on top of their annual membership fees) is around 50€/year. An ASN and a /48 of IPv6 PI space would therefore clock in around 100€/year (which is in line with the GP's pricing).

Membership fees are around 1400€/year, with a 2000€ signup fee. The number of PA (provider assigned) resources you have has no bearing on your membership fee. If you only have a single /22 of IPv4 PA space (the maximum you can get as a new LIR today) or you have several /16s, it makes no difference to your membership fees (this wasn't always the case, the fee structure changes regularly).

(EDIT: Source: the RIPE website, and the invoices they've sent me for my LIR membership fees)

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)...
