@mibullock you didn't know caching existed? i gotta meme more

[Alex Krivit @ackriv]

Range caching used to have a knob nobody could set right!

Too small: floods of tiny origin fetches.
Too big: a few-MB seek could pull 128 MiB from origin.

So we deleted the knob. R2's p99 TTFB was cut in half.

Origin Range Requests, now on every plan:

[Matthew Prince 🌥 @eastdakota]

Amused that AWS just unilaterally cancelled Cloudflare's Reinvent booth. There are always signs when someone finally realizes they're losing. Guess we'll just attend and throw the most fun side events without paying Amazon! Reply if you want an invite.

[Cloudflare @Cloudflare]

As post-quantum signatures threaten to inflate TLS handshakes and certificate transparency logs, Merkle Tree Certificates offer a path to compact, auditable authentication. Cloudflare’s new certificate authority will support MTC issuance at scale. https://t.co/J17lILl00u #BirthdayWeek
