Pakistan's sole under sea optical fiber link, called Southeast Asia, Middle East and Western Europe-3 (SEAMEWE-3), stopped working due to a fault from
27th June to the 8th of July 2005. This disruption halted the global connectivity of almost 10 million internet users in the country. The details can be found here.
Recently Pakistan has connected to SEMEW4 which provides Pakistan with a redundant link in case the outage occurs again. Here is the complete story
http://www.pkblogs.com/pakistan/2006/01/smw4-mitigates-total-blackouts.html Here is a case study of Internet connectivity of NUST Institute of Information Technology (NIIT) that was done in 2004 Internet performance for NIIT, Pakistan Jan - Feb 2004 PERN - Pakistan Education and Research Network is funded by the Pakistan Higher Education Committee (HEC) and is a nationwide educational intranet connecting premiere educational and research institutions of the country. The network provider for PERN is NTC. All land based Internet connectivity is via the Pakistan Internet Exchange (PIE) in Karaci where the fibres come ashore. PIE in turn is managed by Pakistan Telecommunication Compant Limited (PTCL).
In February 2007 Telekom Malaysia announced that the company is set to complete its US$100 million countrywide fiber-optic-backbone project in Pakistan - the largest fiber-optic network in the country - by October 2007. The backbone will link more than 75 major towns and cities in Pakistan. The project is with Multinet ,a Pakistan ISP now a subsidiary of Teelkom Malaysia. It appears this will provide an alternative to PTCL.
Bangladesh
SEMEW4 has greatly affected the internet connectivity of Bangladesh Before this Bangladesh relied on VSAT for Internet connectivity.
Most of the sites now have moved to fiber but some of them are still on satellite. We used our HostSearcher tool which searches for sites on Google.
Out of 20 sites that we located in Bangladesh 3 had min RTT > 500 ms indicating that they are on satellite. Bangladesh has now got 2 STM-1 links with
MCI and Singtel.
