Quote - mine appears ok so far - looks like we might have some DNS poisoning going on somewhere and it hasn't hit me yet

 

I had to look it up because I didn't understand what you meant, but, by golly, this is a real term and it has just really upset me.

DNS cache poisoning ### From Wikipedia, the free encyclopedia

 

Jump to: navigation, search

DNS cache poisoning is a technique that tricks a Domain Name Server (DNS server) into believing it has received authentic information when, in reality, it has not. Once the DNS server has been poisoned, the information is generally cached for a while, spreading the effect of the attack to the users of the server.

Normally, an Internet-connected computer uses a DNS server provided by the computer owner's Internet Service Provider, or ISP. This DNS server generally serves the ISP's own customers only and contains a small amount of DNS information cached by previous users of the server. A poisoning attack on a single ISP DNS server can affect the users serviced directly by the compromised server or indirectly by its downstream server(s) if applicable.
