I wonder how long it will take before anybody actually updates their

still seeing
several hundred unique hosts per hour poking the IP address for time -
like over a decade later.

Would actually be interesting to get a brief update on how many of these
SNTP requests the Madison NTP server still gets.

At the time, Dave hypothesized that the affected devices would have a
half-life of about 5 years - so 10 years on, you would expect this to have
subsided to around 25% of the initially report rate. I wonder if that held
true?
