I'm running a pretty basic Linode VPS and I had to fine tune a few things in order to deal with the increased traffic. I can clearly see a date around the 14-15 where my traffic increases to 3-4 times the usual amounts.From a source network point of view we see devices come online and hit ~35 unique NTP servers within a few seconds. I'll try to see if I can track down what type of devices they are.
I found devices doing lookups for all of these at the same time {0,0.uk,0.us,asia,europe,north-america,south-america,oceania,africa,europe}.pool.ntp.org and then it proceeds to use everything returned, which explains why everyone is seeing an increase.
