Web site access problem
Perhaps the site was taken off line, or the computer hosting it is down for maintenance. However, the cause could be something more mysterious. At any given moment, a portion of Internet traffic ends up being routed into information “black holes.” These are situations where advertised paths exist to the destination, but messages – a request to visit a Web site, an outgoing e-mail – get lost along the way.
Hubble is a system that operates continuously to find persistent Internet black holes as they occur. Hubble has operated continuously since September 17, 2007. During that time, it identified 887,676 black holes and reachability problems.
