The #NANOG mailing list discussed an outage of #Cogent in #Texas. The company's update: "This is being caused by multiple fiber cuts".
Must be lots of stuff going on, if multiple fiber cuts appeared at the same time. Anyone ideas what could have caused it?

Spent a full week trying to get answers from #Cogent about what #T5 is doing with power maintenance & setting up our dual feed power.
Me: Are you supplying the PDUs?
Them...
Them...
Them the day before: No. You are.
Me: YOU'VE GOTTA BE KIDDING ME!
Scramble scramble FOUND!
Me: You'll be there to hook it up.
Them: No. You're doing that.
Me: So i have authorization to lift the floor & energize our PDUs?
Them: Yes, but you dont need to, because you are on the line that isnt going down.

A #rootserver at the #Internet’s core lost touch with its peers. We still don’t know why.
For 4 days, the c-root server maintained by #Cogent lost touch with its 12 peers.
This server, maintained by Internet carrier Cogent Communications, is one of the 13 root servers that provision the Internet’s root zone, which sits at the top of the hierarchical distributed database known as the domain name system, or #DNS.

@LunaRogue depends on the network in question and how well it's interconnected.
For example, you may have double-digit ms on a #5G tower that is fiber-connected, triple-digits if it uses RF links that are pretty clogged and potential timeouts and packet losses with shitty networks like #DTAG since they don't peer on #DECIX and underprovidion their peers abused as upstream|s [#Cogent & #Level3]...
And in some cases, you've to deal with mobile networks of cruise ships that are on #Inmarsat BGAN
