Re: Cloudflare blocking Cogent again

[Mike Lyon via NANOG <nanog () lists nanog org>]

That’s so nice of Cogent to shrug it off. That’s some top-quality customer service right there!

I’ll add this to my ever-growing list of why i will never do business with Cogent.

Suggestions on how to fix? Ditch Cogent.

If you need help sourcing other providers, feel free to shoot me a message offlist.
