It is seen that several hosts exhibit high unreachability. The reasons behind the high unreliability are usually site specific and vary from lack of reliable power and a source of backup power, floods, lack of access to the site when there are problems that require physical access and some stand out due to lack of understanding of the problem.

RTT and Losses for 2010
| | | |
The average of the minimum RTT measured between regions of Pakistan between Dec-2009 and November 2010. Spreadsheet | Various percentiles for the Inter Packet Delay Variation (IPDV or jitter) between Pakistani monitoring hosts and remote host pairs. The line shows the number of pairs with measurements contributing to the results. Spreadsheet | The blue dots are the median losses seen between all pairs of monitoring and remote hosts for each month. The error bars show the extent of the 25 and 75 percentiles. The red dots are the number of pairs contributing to the packet loss measurements. Spreadsheet |
