    We have been using Fastly for the past 4 months with both http2 and http3.

    Anyone use it?
    I'd like to exchange some opinions.

    Unfortunately, haven't had the chance to use Fastly. Cloudflare is what I use and pretty sure alot of Centmin Mod users use Cloudflare as well :)

    Have you used Cloudflare too? Interested to hear your experiences with Cloudflare vs Fastly :)

    Cloudflare we certainly tried it, but it's not satisfactory it's really limited in settings and the cache expires fast despite the apo settings.

    Fastly is another planet.
    Just by comparing the real ttfb you realize.

    Are you comparing apples to applies? Cloudflare paid plans the higher you mean the faster TTFB get. I touched on this in my blog post regarding Cloudflare network prioritization and how it impacts performance What Are The Benefits Of Using Cloudflare Business Plan? - Centmin Mod Blog and also for improving Cloudflare TTFB at https://community.cloudflare.com/t/improving-time-to-first-byte-ttfb-with-cloudflare/390367/

    I don't think Fastly has a free plan so you comparing paid Cloudflare plans?

    We did tests on more of our editorial sites, not forums.

    I can send you an old screen because now the cf enterprise graph is no longer visible.

    anyway here no one uses Fastly I understand...

    Interesting, so that Google Webmaster Console crawl stats show Cloudflare average TTFB slowing over time? Make sure you do not enable Cloudflare Automatic Signed Exchanges or Cloudflare Cache Reserve, as both features can cause slower TTFB. Not sure if you enabled those?

    Been a while since I checked my GSC Crawl stats but

    Here you have the JS of an editorial site.

    Here, however, another site with http3 we found that the scans at one point almost go to zero for 1 or 2 days then start again.

    We use low TTLs of 12 hours maximum, as we have found this to work better on news sites.

    I'm talking about sites that publish 20 to 35 news a day.

    Tiered cache is fine to enable :)

    That's nice and fast so the drop in TTFB times coincides with switch to Fastly CDN and before was Cloudflare?

    Yeah if you update that frequently, need to use more fine grain CDN cache configurations - you could do that with Cloudflare features /API custom scripting too if you configure your site structure optimally too.
