Recent Outages (Last 24 hours)

IODA (Internet Outage Detection and Analysis) is an operational prototype system that monitors the internet, in near-realtime, to identify macroscopic Internet outages affecting the edge of the network, i.e. significantly impacting an AS (Autonomous System) or a large fraction of a country.

Dashboard
Methodology
IODA combines information from three data sources, establishes the relevance of an event and generates alerts. The outage events and the corresponding signals obtained through automated analysis are displayed on dashboards and interactive graphs that allow the user to further inspect the data. See the IODA project page for scientific references and for more information about our methodology.
Global Internet routing (BGP)
We use data from ~500 monitors participating in the RouteViews and RIPE RIS projects to establish which network blocks are reachable based on the Internet control plane.
Internet Background Radiation
We process unsolicited traffic reaching the Merit Network Telescope monitoring a large unutilized IPv4 address block.
Active Probing
We continuously probe a large fraction of the (routable) IPv4 address space from Georgia Tech servers and use a methodology developed by University of Southern California to infer when a /24 block is affected by a network outage.
