HACKERS HAMPER HOLIDAY h.e.l.lO'S By Scott Mason

As most of my readers know by now, I have an inherent suspicion of lame excuses for bureaucratic bungling. If any of you were unable to make a long distance phone call yesterday, you weren't alone.

AT&T, the long distance carrier that provides the best telephone service in the world, handles in excess of 100,000,000 calls daily. Yesterday, less than 25% got through. Why? There are two possible answers: AT&T's official response and another, equally plausible and certainly more sinister reason that many experts claim to be the real culprit.

According to an AT&T spokesperson from its Basking Ridge, New Jersey office, "In my 20 years with AT&T, I have not seen a crisis so dramatic that it nearly shut down operations nation- wide." According to insiders, AT&T came close to declaring a national emergency and asking for Federal a.s.sistance.

Airlines and hotel reservation services reported that phone traffic was down between 65-90%! Telemarketing organizations said that sales were off by over 80%.

Perhaps an understanding of what goes on behind the scenes of a phone call is in order.

When you pick up your phone, you hear a dial tone that is provid- ed by the Local Exchange Company, or as more commonly called, a Baby Bell. The LEC handles all local calls within certain dial- ing ranges. A long distance call is switched by the LEC to the 4ESS, a miracle of modern communications. There are 114 Number 4 and 5 Electronic Switching Systems used in all major AT&T switch- ing offices across the country. (A few rural areas still use relays and mechanical switches over 40 years old. When it rains, the relays get sticky and so does the call.)

Now here's the invisible beauty. There are 14 direct connects between each of the 114 4ESS's and every other 4ESS, each capable of handling thousands of call at once. So, rarely do we ever get a long distance busy signal. The systems automatically reroute themselves.

The 4ESS then calls its own STP, Signal Transfer Point within an SS7 network. The SS7 network determines from which phone number the call originated and its destination. (More about that later!) It sends out an IAM, Initial Address Message, to the destination 4ESS switch and determines if a line is available to complete the call. The SS7 is so powerful it can actually create up to 7 additional virtual paths for the heaviest traffic. 800 numbers, Dial a p.o.r.n 900 numbers and other specially coded phone numbers are translated through the NCP( Network Control Point) and routed separately. Whew! Had enough? So have I.

The point is, ma.s.sive computer switches all across our nations automatically select the routing for each call. A call from Miami to New York could be sent through 4ESS's in Dallas, Los Angeles and Chicago before reaching its ultimate destination.

But what happened yesterday?

It seems that the switches got real stupid and slowed down. For those readers who recall the Internet Worm in November of 1988 and the phone system slowdown in early 1990 and then again in 1991, computers can be infected with errors, either accidentally or otherwise, and forced to misbehave.

AT&T's explanation is not satisfying for those who remember that AT&T had said, "it can never happen again."

Today's official explanation is; "A minor hardware problem in one of our New York City 4ESS switches caused a cascading of similar hardware failures throughout the network. From all appearances, a faulty piece of software in the SS7 networks was the culprit.

Our engineers are studying the problem and expect a solution shortly. We are sorry for any inconvenience to our valued cus- tomers."

I agree with AT&T on one aspect: it was a software problem.

According to well placed sources who asked to remain anonymous, the software problems were intentionally introduced into AT&T's long distance computers, by person or persons yet to be identi- fied. They went on to say that internal investigation teams have been a.s.signed to find out who and how the "bug" was introduced.

Regardless of the outcome of the investigation, AT&T is expected, they say, to maintain the cover of a hardware failure at the request of the public relations Vice President.

AT&T did, to their credit, get long distance services up and running at 11:30 P.M. last night, only 9 hours after the problem first showed up. They re-installed an older SS7 software ver- sion that is widely known to contain some "operational anomalies"

according to the company; but they still feel that it is more reliable than what is currently in use.

If, in fact the biggest busy signal in history was caused by intruders into the world's largest communications systems, then we need to ask ourselves a few questions. Was yesterday a sym- bolic choice of dates for disaster or mere coincidence? Would the damage have been greater on a busier business day? Could it affect our defense systems and the government's ability to commu- nicate in case of emergency? How did someone, or some group, get into AT&T's computers and effect an entire nation's ability to do business? And then, was there a political motivation sufficient to justify am attack om AT&T and not on Sprint or MCI?

Perhaps the most salient question we all are asking ourselves, is, When will it happen again?

This is Scott Mason, busy, busy, busy. Tomorrow; is Big Brother listening?

Friday, November 27 Times Square, New York

The pre-winter overnight snow-storm in New York City turned to sleet and ice as the temperature dropped. That didn't stop the traffic though. Hundreds of thousands of cars still crawled into Manhattan to insure downtown gridlock. If the streets were drivable, the city wouldn't stop. Not for a mere ice storm.

Steam poured from subway grates and manhole covers as rush hour pedestrians huddled from the cold winds, tromping through the grimy snow on the streets and sidewalks.

The traffic on 42nd street was at a near standstill and the intersection at Broadway and 7th Avenues where the Dow Chemical Building stood was unusually bad. Taxis and busses and trucks and cars all fought for s.p.a.ce to move.

As the southbound light on 7th turned green, a dark blue Ford Econoline van screeched forward and cut off two taxis to make a highly illegal left turn. It curved too quickly and too sharply for the dangerously icy conditions and began to slide sideways.

The driver turned the wheel hard to the left, against the slide, compensating in the wrong direction and then he slammed on the brakes. The van continued to slide to the right as it careened toward the sidewalk. The van rotated and headed backwards at the throngs of pedestrians. They didn't notice until it was too late.

The van spun around again and crashed through a McDonald's window into the dense breakfast crowds. As it crushed several patrons into the counter, the van stopped, suddenly propelling the driver through the winds.h.i.+eld into the side of the yogurt machine. His neck was broken instantly.

Getting emergency vehicles to Times Square during the A.M. rush hour is in itself a lesson in futility. Given that 17 were p.r.o.nounced dead on the scene and another 50 or more were injured, the task this Monday morning was d.a.m.ned near impossible.

City-ites come together in a crisis, and until enough paramedics arrived, people from all walks of life tended to the wounded and respectfully covered those beyond help. Executives in 3 piece suits worked with 7th avenue delivery boys in harmony. Secre- taries lay their expensive furs on the slushy street as pallets for the victims.

It was over two hours before all the wounded were transferred to local hospitals and the morgue was close to finis.h.i.+ng its clean up efforts. Lt. Mel Kavitz, 53rd. Precinct, Midtown South NYPD made it to the scene as the more grisly pieces were put away. He spoke to a couple of officers who had interviewed witnesses and survivors. The media were already there adding to the frigid chaos. Two of the local New York TV stations were broadcasting live, searching out sound-bytes for the evening news and all 3 dailies had reporters looking for quotable quotes. Out of the necessity created by such disasters, the police had developed immunity to the media circus.

"That's it lieutenant. Seems the van made a screwball turn and lost control." The young clean-shaven patrolman shrugged his shoulders. Only 27, he had still been on the streets long enough not to let much bother him.

"Who's the driver?" Lt. Kavitz scanned the scene.

"It's a foreign national, one . . .ah . . .Jesef Mumballa. Second year engineering student at Columbia." The young cop looked down and spoke quietly. "He didn't make it."

"I'm not surprised. Look at this mess." The Lieutenant took it in stride. "Just what McDonalds needs. Another ma.s.sacre. Any- thing on him?" Kavitz asked half suspecting, half hoping.

"Clean. As clean as rag head can be."
