Quoting Jose Gerardo Perales Soto <gerardo.perales () axtel com mx>:We've recently experienced a traffic increase on the NTP queries to NTP pool project (pool.ntp.org) servers. One theory is that some service provider NTP infraestructure failed approximately 2 days ago and traffic is now being redirected to servers belonging to the NTP pool project. Does anyone from the service provider community have any comments?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?
IOS uses time.appple.com which is widely available.
