However, you may want more than just apples. I've seen at least three serious providers offer as good or better deals in the last year or so. At one time they were unbeatable from a sheer price perspective, but in my more recent experience, this is no longer true. John

CenturyLink/Level 3 combined AS
by Darin Steffl 10 Jun '19

10 Jun '19

Hey all, Are there plans for CL and Level3 to combine AS's into one network? If not, do they actively peer and route traffic through each other's networks at least? Basically we're looking at picking up 1G of CL and wondering if it's near the same quality as Level3 in terms of latency and packet loss.

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. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

Taobao AS37963 (Alibaba) network abuse
by Tyler Applebaum 06 Jun '19

06 Jun '19

Has anyone ever had success in working with the abuse contact for Taobao? I e-mailed ipas(a)cnnic.cn<mailto:ipas@cnnic.cn> . We were seeing a flood of requests from 42.120.128.0/17. Went ahead and blocked that and a few others to prevent damage, but we're still seeing the ACL hits pile up.
