Another view of the changes is seen in the map below showing the throughputs before (Jan-Sep 2007) and after (Jan 30 2008). Bear in mind that the fact the outage did not start until around 6:00am, and re-routing traffic before the end of the day will both dilute the effect. Also the effects were not uniform on all hosts in a country.
It is interesting that some countries such as Pakistan were mainly unaffected, despite the impact on neighboring countries such as India. This contrasts dramatically to the situation in June - July 2005, when due to a fibre cut of SEAMEWE3 off Karachi, Pakistan lost all terrestrial Internet connectivity which resulted in many cases in a complete 12 day outage of services. This is a tribute to the increased redundancy of international fibre connectivity installed for Pakistan in the last few years.
One can also see the effect by looking at the RTTs for affected hosts as a function of time. This is seen below where we plot the daily RTT seen from SLAC versus the date and the Top Level Domain (TLD) of the country the host is located in. It is seen taht there is a big spike going from around 300 ms to over 1000 ms for January 30th, followed by recovery in several cases. The main countries affected are the United Arab Emirates (AE), Bangladesh (BD), Bhutan (BH), Djibouti (DJ), Indonesia (IN), Jordan (JO), Sri Lanka (LK), the Maldives (MV), Oman (OM), Saudia Arabia (SA), Thailand (TH) and Turkey (TR).
