Cogent has done well to remediate the compromised MikroTik routers on their
network. 3,000 IPv4 hosts were found on Aug. 25 (
https://twitter.com/bad_packets/status/1033256704941514752) and today, only
a hundred:

I guess those bots have to sit somewhere.  I don’t know that they would be
in routers as much as they would be in Microsoft Windows… so if that’s what
you meant, then I see what you mean Michael



Niels, I like my cogent and telia internet connections… I just recall
seeing more ddos on cogent then I did on my previous att, and current
spectrum… telia is showing a good bit of ddos also



Let’s put it this way, I can thank Cogent and Telia for helping my get
better in my ddos mitigation skills  J   … there’s a bright side to
everything huh

Or he's saying that cogent has the biggest network of compromised users.
Usually ipv4 only eyeball networks tend to have the most bots on net.

However Cogent seems to be the dirtiest in regards to DDOS...
however Telia might be catching up... in times past when I receive
volumetric DDOS, Cogent typically ranks with the highest on my
providers ... AT&T and spectrum seem to be a bit cleaner

So you're saying, Cogent and Telia have the best backbones and
interconnects and thus deliver the most of your traffic to you,
even at times of peak utilization?
