To add some more numbers to this, I'm seeing 4x the usual NTP traffic
to my server in pool.ntp.org, starting Dec 13.
Top source ASNs by % of NTP traffic seen by my server (I don't have
pre-Dec 13 traffic by ASN handy)
sprint 4.0%
verizon-wireless 3.4%
tmobile 2.9%
att-wireless 2.8%
comcast 2.1%
orange 1.8%
sky 1.6%
twc 1.0%
att 1.0%
swisscom 0.9%
saudinet 0.8%
virgin 0.6%
opaltelecom 0.5%
qwest 0.5%
eli 0.2%
verizon 0.2%
Possibly related is the new iOS release. Does the new iOS generate
more NTP traffic? Can anyone measure that?
