Re: Question about strain on the A root server

  • From: Dirk Harms-Merbitz

We are seeing a small number of machines that almost do DOS
attacks so many hits are being requested.

It started a few months ago. The number of machines that do
this seems to be slowly increasing.

Could this be a configuration problem in some companies new
DNS server software?
