Description
outages in a sample of IPv4 /24 blocks
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 20k /24 subnets were periodically reprobed. Outages are analyzed and reported on the responses.
