Is the NTP synchronization done with only a single packet? Because otherwise you'll be interrupting connections constantly.

It is UDP, so it is connectionless.

UDP is a Transport Layer protocol. NTP is an Application Layer protocol.

Fair enough, UDP doesn't imply that the application protocol is connection-less, but AFAIK NTP is.

What about amazon lightsail?

It also runs on AWS so even though they try to trick you into thinking you don't pay for bandwidth you do. Also small EC2 instances are throttled so their server would probably not function most of the time.

They include 1TB BW in the $5 instance, that's $90 savings.
