Outage on SMW3
Feb 22nd, 2006 witnessed an outage of 12 hours (from around 8 in the morning till the evening) due to an optical fiber cut somewhere within Karachi.
Pakistan Internet Exchange shifted its traffic to other providers that had their circuits terminating via the SMW4 undersea optical fiber cable - thus saving the masses from a complete blackout. This is in-line with the expectations assosiated with the availability of an alternate connection from Pakistan to the outside world.
Unfortunately, some bigger ISPs who were relying primarily on circuits being terminated from SMW3 suffered a lot causing the pain to reach the end users. Smaller ISPs who were on PIE, fortunately, chugged along happily during this outage.
