|longDesc                  |To collect this data, a subset of Internet IP address blocks were pinged by   |
|                          |sending ICMP ECHO_REQUEST (PING) packet. The response (if it ever came within |
|                          |11 minutes time interval) was recorded in this data set. Probe was repeated   |
|                          |every 11 minutes. In all, approximately 2.5 million /24 subnets were          |
|                          |periodically reprobed. Outages are analyzed and reported on the responses.    |

Dataset Contents

   README.txt           copy of this README
   outages_all.it1w.bz2 responses and outages of all subnets probed during
                        this survey
   data/
   *.bz2                binary data files of icmp replies

   Subdirectory "data" contains four bzipped binary files containing probe
   records.

Data Format

   Binary format of trace files is described in detail here:

   http://www.isi.edu/ant/traces/topology/address_surveys/format_outage_survey.html

Collection Method

   Data collection involves pingging a fraction of allocated address blocks.
   Full description of this method is in:

     Lin Quan, John Heidemann and Yuri Pradkin. Detecting Internet Outages
     with Precise Active Probing (extended). ISI-TR-2012-678. February, 2012
     http://www.isi.edu/~johnh/PAPERS/Quan12a.html.

   This specific work involved probing 20 addresses in each of about 2.5M /24
   blocks for about 24 hours.

   Using icmptrain, the tool described in:

     John Heidemann, Yuri Pradkin, Ramesh Govindan, Christos Papadopoulos,
     Genevieve Bartlett, and Joseph Bannister. Census and Survey of the
     Visible Internet. In Proceedings of the ACM Internet Measurement
     Conference, p.169-182. Vouliagmeni, Greece, ACM. October, 2008
     http://www.isi.edu/~johnh/PAPERS/Heidemann08c.html.

  Probing Location(s)

   The probing locations for outage surveys are indicated in their names. A
   "w" means west, which is from isi.edu in Marina del Rey, California; "c"
   means center, from colostate.edu, in Ft. Collins, Colorado; "e" means east
   which is from east.isi.edu, from Arlington, Virginia.

   See Dataset Contents for more information on the system who did the
   survey.

  Beginning/Ending Date and Time Zone

   Dates/Times specified in the metadata are in UTC.
