is Cloudflare D1 replicated?

i just tried https://speedvitals.com/ttfb-test?url=https://northwind.d1sql.com/products?_data=routes%2Fproducts and the latencies do not seem to reflect replication, the latency seems quite beyond what I would consider "edge". even without D1, im seeing close to 100ms, mid 50s in other regions outside north america. can you please explain?
