Why is the commit frame not sufficient to determine whether the transaction was fully written or not? Is there a scenario where the commit frame is fsynced to disk but the proceeding data isn't?
The disk controller may decide to write out blocks in a different order than the logical layout in the log file itself, and be interrupted before completing this work.

I thought Cloudflare was going to provide "Always Online" access to Internet Archive

Other way around! Cloudflare can optionally load your site from IA if it's down.

In the US they had a module replacement that upgraded the cellular modem to 3G, I believe. Wonder why they aren't doing that in the UK as well?

Always thought QMail was the best option back when Postfix came out, but it certainly has won the top spot over time.

Naive question, and I hope someone more knowledgeable than me can enlighten me here;
Why are we even testing for superconductivity with levitation, instead of just checking for current loss/heat loss while conducting?
The samples are super small and not homogeneous, so its tough to get any kind of accurate reading with probes, is my understanding.
I wonder how feasible it would be to keep cold assets on Backblaze B2 and automatically move them to R2 if they get hot enough.
Better yet, seeing as how you get free transfers between Backblaze and Cloudflare, I wonder if the 10ms cpu limit on free workers (or 50ms paid) would be enough to do the entire process on CF's servers.
The blog post seems to indicate that there will be an automatic way to move assets to R2 from a S3 compatible service. I haven't gotten access to R2 yet so no idea what settings they have.
"To make this easy for you, without requiring you to change any of your tooling, Cloudflare R2 will include automatic migration from other S3-compatible cloud storage services. Migrations are designed to be dead simple. After specifying an existing storage bucket, R2 will serve requests for objects from the existing bucket, egressing the object only once before copying and serving from R2."
