In addition pinger.isra.edu.pk does not respond by name.
Is it time to start paring down the list of PingER monitor hosts in Pakistan, starting with those that have been down for a while and despite your efforts they are not cooperating. One might also look at the coverage by region in Pakistan and try and keep good coverage for all regions.
PingER at SLAC
Thiago has modified ping_data_plot.pl and frequency.pl to provide much improved GUI for the plots. This has been very useful for plotting the differences between pinger.slac.stanford.edu and pinger-raspberry.slac.stanford.edu. See ePinger Project at SLAC which we are putting together.
The Raspberry Pi at SLAC has been running smoothly since June 11th. We have power cycled it a few times to ensure it works across power outages. It is also accessible from ssh.
the data is available at http://www-wanmon.slac.stanford.edu/cgi-wrap/pingtable.pl?file=average_rtt&by=by-node&size=100&tick=daily&year=2015&month=06&from=EDU.SLAC.STANFORD.RASPBERRY&to=WORLD&ex=none&only=all&dataset=hep&percentage=any

We have a We have a 4 host cloud with~16Gbytes each, plus access to 220Gbytes each, Thiago is working with SLAC system people to set it up. Thiago is also working with Renan to configure things to use Hadoop and Impalawith SLAC system people to set it up. Thiago is also working with Renan to configure things to use Hadoop and Impala.
Bebo is interested in providing PingER data of measurements to www web servers to the Web observatory (see http://webscience.org/web-observatory/). To assist in this I have added a search term to pingtable.pl to select just remote hosts with www in the name. There are 365 such hosts. The URL appears as:http://www-wanmon.slac.stanford.edu/cgi-wrap/pingtable.pl?file=average_rtt&by=by-node&size=100&tick=monthly&from=EDU.SLAC.STANFORD.N3&to=WORLD&ex=none&only=www&dataset=hep&percentage=any where only=www does the selection.
