Whoa, nice error:

    Server Error in '/' Application.
    The process cannot access the file 'C:\Users\www.womble.co.za\cable_map\landing_stations.js' because it is being used by another process.

    Line 236:  public void PutFileContents(string filename, string txt)
    Line 237:  {
    Line 238:      TextWriter tw = new StreamWriter(filename);
    Line 239:      tw.Write(txt);
    Line 240:      tw.Close();
It seems that there is a race condition where each web request tries to open this file, and Windows doesn't let you have the file open multiple times (at least with the chosen options).

How vulnerable are the cables to physical attack (i.e., drag something heavy and sharp along the ocean floor)?

There is also at least one submarine out there that has probably been modified to access submarine cables:

Why is there a 5TBps line from the northern part of mainland Norway up to Svalbard? Is there much telecomms there?

NATO defence installation, maybe?

No. From Wikipedia:

"The Spitsbergen Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone."

and

"Svalbard is a demilitarized zone, as the treaty prohibits the establishment of military installations. Norwegian military activity is limited to fisheries surveillance by the Norwegian Coast Guard. The treaty requires Norway to protect the natural environment."

I remember Egypt getting cut off as quite a big story here (UK), http://dailystaregypt.com/article.aspx?ArticleID=18746

Google it, it seems to happen every few months but most countries have some limited backup.

Latest appears to be this one, http://allafrica.com/stories/201007290937.html
