Does Cloudflare have any competitors yet?

CloudFlare is much more than a CDN.

Perhaps Google PageSpeed Service, if they ever launch? https://developers.google.com/speed/pagespeed/service

DOSArrest predates Cloudflare and does a fantastic job of DDOS mitigation. But they are not cheap.

Akamai?

Apples and oranges.

Akamai recently deflected an attack on the scale of 1 TBit/s and is present in pretty much every DC (~1000 POPs). CloudFlare has 23 POPs and brags about handling 65 GBit/s...

Do you have a source for the 1 Tbps attack? I'd like to read about it, but my search came up empty-handed.

:-)

there are some public studies on DDOS size over the years. IIRC Arbor networks published some numbers earlier this year. IME tens of Gb/s is a mid size attack these days. Large is a hundred plus Gb/s.

I can't find any public reports topping ~100 Gbps. For example, here's a recent article that interviewed an Arbor employee and mentions a ~100 Gbps plateau:

Hrm, maybe Im misrembering. Found akamai claiming 125Gb/s in '09, and some more arbor quotes of ~110Gb/s. I'll see if I still have the report Im thinking of tomorrow.

Only a sales rep bragging to me on the phone.

He could have been lying but considering how uptight Akamai is about everything I doubt he made it up.

Akamai got into that many POPs by "giving away free bandwidth saving appliances" to the ISPs rather than paying to host their commercial edge CDN in a their DCs. Full marks to whoever came up with that spin! (This was circa 1999/2000).
