Fastly's ISP providers


#1

Fastly is extremely selective in choosing our vendors, especially our ISP partners.

As a general rule, Fastly only partners with with Tier 1 network providers, and chooses our POP (datacenter point of presence) locations at major interchange points to maximize ISP connections per datacenter.

You can see some of our ISPs in action just by running:

  • traceroute www.fastly.com
    or
  • mtr -c 20 -w -r www.fastly.com

This was my readout from a test:

In this example you can see cogentco.com for Cogent.

The wikipedia article for Tier 1 network providers is superb, and easy to understand even if you’re not a full time network engineer.
