Great article, thanks.. a couple of points though
First off - the SMTP issue - how sure is the user that the issue was network-related and not a result of trying to use an ISP's un-authenticated server? Just a thought.
Secondly - I really dislike when govt/companies/etc. try to protect us from our (im)moral selves. Blocking "pornographic and alcohol-related destinations"? Excuse me?
What about tobacco-related destinations? and other drugs? and how about Nazi-related material or "terrorist" propaganda sites?
And from a non-moral but purely academic perspective, what if someone were to be accessing an alcohol-related website for research purposes.
I may be taking this to the extreme but come on. Why stop at alcohol when they can just censor everything they consider "bad" on our behalf like China does so thoughtfully for their beloved citizens.
Oh, but seriously good speeds
Disclaimer: I'm not saying this because I'd like to use it for downloading porn or alcohol... you know, living on the other side of the country and all.
