Exactly, we use multiple CDNs. We are the only project to do that. This is why our performance and uptime will be always better.
Better than Akamai? I think not.
Akamai does not offer a public CDN. So they are not a competitor. Apples and oranges
If by "public" you mean free, correct.
Akamai is cadillac of the CDN world so more like Apples and Organic Gourmet Apples.
Just be careful with those benchmarks, cdnperf is run by jsdelivr. An uptime and speed monitor based in one location is a pretty flawed way of analysing the performance of a cdn. As for Jimaeks comment above "multiple cdns" do not enforce better performance either.
I guess they are using Pingdom which has more than 50 locations for testing, but yes it would be nice to see per-location data.
This is correct. cdnperf uses multiple locations provided by pingomd and also makes sure all CDNs are tested from the exact same locations.

Thanks for the link, we will be experimenting with cdnperf in the coming weeks, and make the move if we are happy with it.
