On 18 July just as Code Red was starting to scan for vulnerable web servers, a CSX train carrying hazardous materials was derailed in the Howard Street tunnel in Baltimore.

The derailment and subsequent fire severed cables running through the tunnel used by seven of the biggest net service providers to swap data.

These companies started reporting disruption to the usual running of the net just as Code Red was hitting its stride, leading many people to assume that the worm was doing the damage.
