I made a DNS propagation checker that shows the 24 sources as a box of donuts

It queries \~20 geographic vantage points (Google DoH + EDNS Client Subnet) and four public resolvers in parallel, one donut per source. Full box means every source agrees. Empty holes are the ones still serving your old record.
There's a normal grid view too if you just want to read values. Built it because I kept refreshing whatsmydns during migrations.
