D1 (the ability to query your database at the edge) didn't get knocked offline during that outage though?
My concerns, and this is very much my own concerns with no context of what has or is happening internally st Cloudflare, is that the outage exposed some serious issues that will take time to fix safely. The fact that D1 still doesn't support replication is an indication to me that it has been deprioritized, likely with other newer and less used products, while the infrastructure updates are dealt with.
My guess is that they wanted it for 1.0 but the release slipped. It happens.
D1 is definitely not deprioritized. We're heads down on replication, and it's important for us to get it right. Takes time!
