Is there someone from GTT on list that can contact me in pvt?
For over a week we have been seeing loss and latency between Frankfurt and
Milan as reported in outages by Lukas

Yes, pinging public DNS servers is bad.
Googling didn't help me find anything.
Are there any authoritative resources from said organizations saying you

In response to feedback from operational security communities,
CAIDA's source address validation measurement project
(https://spoofer.caida.org) is automatically generating monthly
reports of ASes originating prefixes in BGP for systems from which
we received packets with a spoofed source address.
Came across some endpoint behavior that caused some confusion with a MAC
authentication bypass (MAB) setup, and I was wondering if this is some kind
of well known behavior.
The endpoints (Pure storage arrays) are using the expected MAC addresses,
both fixed and a “virtual” shared MAC for 99.9% of

Why not using RIPE Anchors, which are made to be pi
I'm not looking to do the pinging myself. I have my own destinations I use. I

I'm not sure that an ' authoritative resource ' is really needed. It should
be generally understood at this point in the internet's life that networks

Hi all,
I'm looking for a fiber contractor to trench some fiber on private property

What irked me today was an equipment manufacturer. I found out because Google
had some issues handling ICMP to their DNS resolvers today and some of my
devices started spazzing out.
There's no reason this manufacturer doesn't just setup a variety their own
