It's worth checking the logs to make sure that they agree with what you
expect.

The server is required (by RFC 2136 section 3.6) to update the serial
number after an UPDATE. I would not expect any delay unless the server is
in the middle of a lot of updates and has reached a notify or transfer
rate limit - the logs should tell you if that has happened, or if there
are any ACL-related problems.

Slight or moderate, becoming mainly slight. Fair. Good.
