Introduction
PERN (Pakistan) was the first South Asian country connected to TEIN3. It was connected in late 2008 thanks to a NSF/PERN funded 155 Mbps link to TEIN3 in Singapore. However looking at the traceroutes from Sri Lanka to Nepal, India and Pakistan, while the former two were connected by TEIN3, PERN in Pakistan was connected through the commodity internet.

The reason being that the IP addresses of our web servers are not being advertised on the TEIN3 network because of current bandwidth between TEIN3 and PERN2. The bandwidth of our TEIN3 link has being fully utilized by our research institutes, and we are at maximum utilization of the TEIN3 link. Due to the lack of bandwidth availability we have not made the PERN website available from TEIN3 network. That is the only reason for PERN website not being seen from the TEIN3 cloud.
On the other hand one can see from a plot of ping Round Trip Time (RTT) from SLAC to NCP (see below) that during the month of October 2008 the RTT dropped from over 360ms to under 310ms. 
Looking at the other Pakistani universities the median RTT seen from SLAC to about 18 Pakistani universities dropped from about 370ms to under 320ms between oct 2008 and April 2009, see below:
