" A major breakdown in Southern California's air traffic control system
last week was partly due to a "design anomaly" in the way Microsoft
Windows servers were integrated into the system, according to a report
in the Los Angeles Times.
 The radio system shutdown, which lasted more than three hours, left 800
planes in the air without contact to air traffic control, and led to at
least five cases where planes came too close to one another, according
to comments by the Federal Aviation Administration reported in the LA
Times and The New York Times. Air traffic controllers were reduced to
using personal mobile phones to pass on warnings to controllers at other
facilities, and watched close calls without being able to alert pilots,
according to the LA Times report.
 The failure was ultimately down to a combination of human error and a
design glitch in the Windows servers brought in over the past three
years to replace the radio system's original Unix servers, according to
the FAA.
 The servers are timed to shut down after 49.7 days of use in order to
prevent a data overload, a union official told the LA Times. To avoid
this automatic shutdown, technicians are required to restart the system
manually every 30 days. An improperly trained employee failed to reset
the system, leading it to shut down without warning, the official said.
Backup systems failed because of a software failure, according to a
report in The New York Times.
 The contract for designing the system, called Voice Switching and
Control System (VSCS), was awarded to Harris Corporation in 1992 and the
system was installed in the late 1990s, initially using Unix servers,
according to Harris. In 2001, the company completed testing of the VSCS
Control Subsystem Upgrade (VCSU), which replaced the original servers
with off-the-shelf Dell hardware running Microsoft Windows 2000 Advanced
Server. The upgrade was installed in California last year, according to
the FAA.
 Soon after installation, however, the FAA discovered that the system
design could lead to a radio system shutdown, and put the maintenance
procedure into place as a workaround, the LA Times said. The FAA
reportedly said it has been working on a permanent fix but has only
eliminated the problem in Seattle. The FAA is now planning to institute
a second workaround - an alert that will warn controllers well before
the software shuts down.
 The shutdown is intended to keep the system from becoming overloaded
with data and potentially giving controllers wrong information about
flights, according to a software analyst cited by the LA Times.
 Microsoft told Techworld it was aware of the reports but was not
immediately able to comment."
Un Maramao che il prossimo che mi dice che Win è affidabile lo mando in
Inghilterra a mie spese ad imparare l'inglese. :P

An it harm none, do what ye will.

 Win è affidabile: dove mi fai trovare il biglietto?
E' provato: "spese pagate" fa ai genovesi lo stesso effetto che la
pioggia di ottobre fa ai funghi. :P
Un Maramao che lui non ha mai parlato di biglietto ma di "spese"
generiche. In questo caso trattasi di costumino slip marca Posillipo che
difenderà dai marosi i santissimi mentre raggiungi la perfida albione a
nuoto. :P

Oh, a proposito! Ma sai che ho conosciuto una tua discepola in iChat
qualche ora fa? Mi ha fatto una ottima impressione, è riuscita a far
crashare iChat nel bel mezzo di una disquisizione sul come taluni
architetti di grido mutino da persone fisiche ad intangibili loghi... :P
