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? Dirk On Sat, Apr 22, 2000 at 11:56:37AM -0400, Nick Patience wrote:
Hi all,
Disclosure: I'm a journalist with a company called the451.com (details in sig file).
Anyhow, that said, I was talking to Network Solutions about their decision to swap out the Sun box that is the A root server and change it for a more powerful RS/6000 S80. Also it is using IBM servers for its new network of name servers - it has already deployed 8 of the intended 12 according to the company, including one brought on stream two days ago in Hong Kong.
As most on this list probably already know, it is separating the root servers from the name servers.
Anyhow, NSI claims that the strain on the A root server has jumped from 220 million 'hits' to 420 million during Q1 alone. I haven't managed to define what hit is yet but intend to at some point.
NSI seems slightly unsure as to the main reason for the increase in hits, but speculates that one of the reasons may be says the main reason for this is that ISP's are using different caching techniques and more & more searches are going right to the top of the tree than before.
What do people on this list feel about this as a reason? It seems a little woolly to me.
Cheers,
Nick
