Main content:

  There has been a lot of news regarding Syria’s Internet shutdown that lasted for over 2 days before service has been restored on Saturday. One item that has not been covered in detail is traffic going *into* servers hosted within Syria and how they were affected.

  While monitoring this case firsthand we saw that on Thurs. Nov 29th 10 a.m. UTC, there was a sudden rise in the number of failing DNS queries (servfail DNS response) to domains whose name servers are hosted in Syria. These failing queries kept rising, ultimately reaching a peak at 4 p.m. UTC on Fri. Nov 30th.
