It's not the spike, it's probably a combination of:

- a routing imperfection (this things need to be tweaked over time).

- the fact that we didn't deploy our PoP in India yet (coming this month).

Can you talk to us on the chat if you have some time? It would help to do some debugging.

Great idea for service, but it has to be lightning fast to be in the middle of thousands of requests a minute as someone is surfing the web without making the web feel sluggish.

In NYC on the largest metro ISP. Earlier in the day, was getting 25-43 msec to the typical major DNS providers (1.1.1.1, 4.4.4.4, 8.8.8.8, 9.9.9.9, as well as AdGuard), and usually 71 - 73 msec to you.

After a while, started getting as slow as 280 msec to you.

Last hour or so, mostly just getting timeouts to you, making the web, as well as apps, unusable.

Had to revert.

AdGuard DNS:
