#DNS C #root server is not available from German DTAG #Telekom network, see https://atlas.ripe.net/measurements/160469688
The C root server is from #Cogent . Is that again some Telekom-Cogent rendevous?

Looks like #Cogent made a typo and paths show 174 1 174 :)

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?

@f2k1de @Lili keine Ahnung, aber soweit ich weiß machen die massives #TrafficShaping und #QoS weil #Telekom hat halt so schlechtes #Peering dass deren de-facto #Upstreams (#Cogent & #Level3) die verklagt hatten.

@qwertyoruiop the fact that #DTAG has a testing server that fast is surprising.

Normally #DeutscheTelekom's core network is so #underpeered that they got sued by #Cogent & #Lumen nee. #Level3 for insufficient capacity and abusing them as #upstream|s.

In return, I'm surprised they only got #10G there. I would've already expected #100G and #OM5 fiber everywhere...

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.

That was special. Having to scramble to bring down a hundred virtual machines, then the hardware, right in the middle of restoring from backups. Thanks #Cogent, you lying, incompetent, fucking shitbags. Let me tell you the odds we renew our contract. Zero, and sub-zero. Did we save money on your Kmart pricing? Well, the old saying is true, there's nothing more expensive than a great deal. #sysadmin

#sysadmin weekend from hell.
Thanks #Cogent. Thanks for telling us the "testing" which "shouldn't affect our colo service" was actually a planned power outage that your operations people KNEW would bring down all hardware in our racks on a Friday evening.
Oh! And thanks again, for sending out an all clear on Friday night & again on Saturday, then Sunday, while in hour 30 of restoring our entire infrastructure, being told randomly by a contractor the power was going down AGAIN in 15 minutes.
