Internet Outage Detection and Analysis

Public and private sector stakeholders around the world seek ways to
ensure that the Internet provides the level of reliability and
resilience we have long taken for granted from the telephony network.
Unfortunately, in spite of the societal and economic impact of Internet
connectivity disruptions, we lack near-realtime, scalable, and validated
methodologies and tools to identify and understand large-scale Internet
outages. Based on experimental work in which we combined measurements
at the control plane, active probing, and passive traffic analysis, our
research group is developing an operational prototype system that
monitors the Internet, in near-realtime, with the goal of identifying
macroscopic Internet outages affecting the edge of the network, i.e.,
significantly impacting an autonomous system or a large fraction of a
country. OTF's support allows us to 1) improve IODA's underlying
technical design, 2) make it more useful to the public by improving its
user interface, 3) publish reports about significant Internet outages,
and 4) engage in outreach to teach people about IODA, and collaborate
with other projects.
