Fastly S-1
As a user, Fastly is really, really good. Akamai is the only serious competitor, but they are a lot more traditional in their sales and configuration. (You can theoretically use Azure as a middleman as some have pointed out, but they don't support custom SSL, and configuration changes take literally hours-to-days to propagate.)Cloudflare is fine but they are still an order of magnitude slower, which is why we switched. I just tested and Cloudflare is still taking 48ms their own DNS server to resolve our Cloudflare-hosted DNS, but only 14ms for Fastly to establish a connection and send the first byte.That speed does make a difference. When we switched from Cloudflare to Fastly we had about a 7% increase in completed sales.I think their ROI is still too low for most small businesses, the only way that actually makes sense for us is because it's free for open source/nonprofits. But I can imagine it's a big deal for larger ones.
