Re: ISPs could mitigate this
"People running equipment on the net that is caperable of causing harm to others should be held to account. Pass the bill on to them, with a fine, perhaps even make them go through a training course to show they are fit to let their hardware loose onto the the wider world."
Groan. That's what we'll do. Imagine how well that'll work when your 94 year old grandad gets a virus on his iPad that causes issues out on the Internet.
Of course it SHOULDN'T be down to ISP's to sort this, but at the end of the day, it HAS to be! What other way is there? Those with the know-how should be able to request "unfiltered" connections if they so wish, for the rest, blocks as described by the previous poster should be the norm - same as how parental controls are until an adult unlocks them.
I appreciate in this case it'll only be sysadmin's unleashing a memcache problem, but in other cases, IoT etc, we all need some protection from what's out there. And would you rather ISP's took that on board and made your connection inover a little safer, or would you rather all in sundry could just have their connections doing whatever they like because they're still waiting for their "training course" coming up?
You could argue the same with traffic lights and give way signs out on the road.. "Why make someone else responsible?".. Well because without them, a number of folks would run riot!
