comment How do web-servers “listen” to IP addresses, interrupt or polling?
I can't believe something as complex as this can be summarized so clearly and simply, but you did it. +1

comment How does HTTP become stateless?
Right, I didn't say all. I said some. I personally prefer to avoid sticky sessions, and if possible, avoid sessions altogether. Nevertheless, software exists that doesn't live up to everybody's ideal.

In the TCP/IP model, TCP does not live in the network layer. It lives in the transport layer on top of IP, which is in the network later. The first google hit for "TCP model" demonstrates this: technet.microsoft.com/en-us/library/cc786900(v=ws.10).aspx

can also easily be handled by different server and the client will never know Though technically true, this is misleading as many web applications use sticky sessions, requiring a load balancer to route future requests from the same browsing session to the same server. From an HTTP perspective, sessions are irrelevant, but your last sentence sort of implies that the end-user experience will be unaffected, which would be false with sticky sessions.

comment Is it possible to ping an address:port?
Excellent suggestion. I used to use this to test if a web server was up when a web browser was not an easy option.

comment What is a external reliable IP address to ping to check if internet is available?
The trouble with this is that the servers you are pinging are dedicated DNS servers. It's common for servers dedicated to a specific purpose to block ping requests (ICMP echo). Google's DNS servers do answer to ping, but is that reliable? I'm not sure that a DNS server responding to ping is a future-proof test of "Is the Internet reachable?"

comment Still receiving windows XP updates… Is this expected behavior?
"Additionally, I would find it very hard to believe that malware could inject itself into the Automatic Updates engine and masquerade as an update advertised alongside legitimate updates." That sounds like a brilliant idea for malware writers. I'm sure it can be done too. Why not?
