the fragile internet
we all take the internet for granted, and only realise the fragility when its broken.
not sure how many pple know, the internet is actually extremely disorganised. it simply consists of many separate servers run by a whole gamut of companies, each linked to another by ethernet cable, fibre optic cables to the deep sea kind (that link continents together). theoretically with the graph theory, u can take out any link since theres always another path from one node to another. but reality is there are bigger pipes and smaller ones. when the big pipes disappear its almost as good as gone.
level 3, a major backbone linking up major ISPs inside US and to europe as well seems to be down for the past 2 hours. webcamming was horrid as latency couldnt be maintained. msn and skype just kept dying and dying and dying... some sites were not accessible, or were intermittent. like zdnet.co.uk (based in uk) and logmein (prob hosted too tightly to L3). and there are so few sites offering information on the network status.
i call sbc dsl tech line to complain and hope they are doing sth abt it (they can reroute traffic around broken connections). but the low life tech prob dont know what im talking abt.
its time for the big boys to earn their keep. FIX MY INTERNET!!!
