I looked up what a “tier 1 provider” is and it’s not any clearer really. This image is supposed to explain it apparently.

I mean, that image is on a wiki page. Just scroll down to the "List of Tier 1 networks" section for examples. :P

I get that they’re companies but I don’t understand what they do. Like with josh getting kicked off those tier 1 providers.. how does that even work?

Oh. Well, I guess in that scenario, they're the ultimate gatekeepers to all of the various servers around the world.
Like, depending on where you are in the world and where your destination server is, if you're both on different Tier 3s, you have to go through your 3 to a 2 then a 1, then back down to a 2 that leads to the 3 where your destination server is. If a Tier 3 says "you shall not pass", but the 2s and 1s say it's okay, you can just get a new 3 to access the 2s and 1s. If the 2s say no, it's a little more difficult to get a new 2 to get to the 1s. But if the 1s say nay, you're kinda screwed.

But how do you get their internet? Like when josh got the new tier 1, how did he connect to it? And why don’t the other tier 1s that banned him just ban access to his server?

I would imagine they had a router that they gave him (like how residential ISPs have routers they offer their customers) that would allow for direct access to a Tier 1.
I don't know all the details for his story. Did only one of the Tier 1s block him, but they others don't have him blocked?

I don’t know the full details either but I think he had to use one in Europe. But crunklord said the kfcc server has to be shipped somewhere.

How do you peer with them though?

Wiki page explains it pretty well. Settlement free is the key term. Pretend you and I are both ISPs. You are a large enough ISP that all other ISPs wish to peer with you for $0. However I am a smaller ISP and when I say, how about we have a settlement free peering agreement they laugh in my face and say "no you gotta pay". That makes you tier 1 but me tier 2 (or lower) even if I have settlement free transit through all of my other interconnects.

Google isn’t tier 1? That’s surprising.

You mean as a customer? OK you will have a residential ISP. If for example this was ATT then this is also a tier 1 ISP. In the majority of cases it will not be tier 1 though. So lets say your ISP is google fiber, they will have a paid peering agreement with either a tier 1 network or a tier 2 network that has peering with tier 1 etc.
The peering itself wasn't the issue for KF, it's that they shouldn't be interfering with the traffic for other customers. You might have Centurylink/ lumen as your ISP and they may choose to block routing to kf as a residential customer but that block would not usually occur for commercial transit. That was why this was unusual.

I’m like 99% sure josh said they wouldn’t peer with him though. He had to find a tier 1 in Europe.

While google/ alphabet has both isp and voice services they are not primarily a telco so it really isn't surprising. Remember tier 1 is a *globally* small list.

What’s gae?

He may have wanted a direct connection to a tier 1 for whatever reason. Whoever he connects to directly tier 1 or otherwise can kick him off for whatever reason so it's likely he wanted to be at arms length from the GAE.

I think it’s a psyop tbh.

@bot Is this the mysterious "the cloud" I've heard so much about?
