Isn't 700 changes a second like... really low, considering their scale and amount of domains they manage ?

I have been wondering if the memory scarcity would lead to a desire to optimize software to be more efficient. Curious what the R&D / efficiency development ROI is on reducing memory footprint. I suppose we should both consider current ROI and near future ROI (as the price of memory will likely stay high for at least another 1-2 years).

Cloudflare doesn't get enough credit for their series of overall great technical blog posts.

I'm very curious about the bugs (before vs. after relational) that come from an improvement like this over time

I used to use cloudflare dns, but the same cloudflare harassed me the entire day testing if I'm a robot. The harassment ended after I switched the dns server. See you never again, clouflare
