"Slow" speed for Fastly in Portugal, with NOS and Vodafone

Network Services
1

Hello for all the members and for all the Teams at Fastly,
I am an indirect user of the Fastly CDN network, and I am located in Portugal.

I have noticed that when I need to download something from Fastly’s network (such as Epic Games), the speeds are inconsistent and appear to be limited.

As far as I know, I am using the LIS (Lisbon) Servers, because of the latency I have for one of the endpoints:

Tracing route to dualstack.reddit.map.fastly.net [151.101.1.140]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  10.0.0.1
  2     6 ms     6 ms     6 ms  78.130.32.1.rev.optimus.pt [78.130.32.1]
  3     *        *        *     Request timed out.
  4     *        *        *     Request timed out.
  5    10 ms    10 ms    10 ms  151.101.1.140

The speed I get using Fastly’s Debug website is 127.66 Mbps, which is not too slow, but not the full potential that my ISP can offer (NOS Comunicações, 1Gbps/400Mbps contract, consistent speed even for international routes).

I can also replicate this issue with Vodafone, having a symmetric 1 Gbps contract. I can’t test Altice/MEO service because I don’t have one installed at home, only NOS and Vodafone.

I think NOS peers with Fastly using DECIX Lisbon, and Vodafone peers using GigaPIX.
