The Sept. 11 terrorist attacks on the World Trade Center caused a
significant amount of damage to America's telecommunications
infrastructure. According to a new study, protecting the network has
become a high priority in the months following the attacks.

The study, by research firm Cahners In-Stat/MDR, called Sept. 11 the
"biggest catastrophe" ever to hit the nation's telecom infrastructure.  
According to Henry Goldberg, a senior analyst with In-Stat, three
service providers were "hit hard," while a fourth - AT&T -suffered
significant damage to its local network capabilities in Manhattan.
"Verizon had the most severe damage, Genuity lost a POP, a point of
presence, and Equant also was hit," said Goldberg. "Verizon's West
Street central office was heavily damaged. Walls were broken, dust and
dirt got into equipment, it had a loss of commercial power supply, and
debris made some equipment inaccessible."

"Verizon told me it will take $1.7 billion to $1.9 billion to restore
things to where they were before Sept. 11," he added.

Many large companies are reevaluating disaster recovery plans after
seeing the damage the attacks caused, said Goldberg. "They don't
believe their previous plans are necessarily adequate in this new

The federal government is also getting involved. According to
Goldberg, the National Telecommunications and Information
Administration (NTIA), which is a part of the Department of Commerce,
and the Federal Communications Commission (FCC) are two agencies
spearheading the drive to review security procedures for the telecom

"There also is the Network Reliability and Interoperability Council
(NRIC), which is chaired by Joseph Nacchio, CEO of Qwest," he said.  
"However, the government is limited in what it can do, because
companies are hesitant to disclose information in public."

Telecom companies have changed many things since Sept. 11, said
Goldberg. Before the attacks, the emphasis was on consolidating
operations into fewer places to increase efficiency. Post-attacks,
companies don't want one location's failure to bring down traffic, he

"Verizon had a heavy concentration of traffic in one place - its
central office in Manhattan. Now, they are diversifying so all the
switching equipment is not in one place," he explained.

Telecom companies are also implementing extensive new security
procedures at their central offices, Goldberg added.

"Equant is paying more attention to routing when obtaining capacity
from third-party carriers," he said. "Genuity never anticipated an
entire POP could be destroyed. Now, they are making sure they have
redundancy in routes and POPs. The redundant paths go through
different POPs."

Another reaction to the attacks is the rise of "business continuity
services." Goldberg said these "portfolio" services are offered by
telecom service providers as a way for companies to not have all of
their data and infrastructure in one vulnerable place.

Business continuity services include virtual private networks (VPN),
firewalls, intrusion detection, external hosting, storage and Internet
data centers, he said.

"The application hosting would take place in the provider's secure
centers, offering back-up hosting and storage," said Goldberg.  
"Service providers say customers are expressing interest in these
services after Sept. 11. SBC offered these services before the
attacks, but now AT&T and Verizon do as well."
