I noticed now many customers using tp-links reported issues with
internet connection.
Analyzing internet traffic, i noticed that tp-link seems excessively
requesting ntp from those ip addresses, and not trying others:
> 192.5.41.40.123: NTPv3, Client, length 48
> 192.5.41.41.123: NTPv3, Client, length 48
> 133.100.9.2.123: NTPv3, Client, length 48
I'm asking customer to make photo of device, to retrieve model and
revision, and checking other customers as well, if they are abusing same
servers.

I also have a similar experience with an increased load.
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.
I did a quick dump and in 60 seconds I was hit by slightly over 190K
IPs
