2008 September 14th (day) cause of the system failure which occurs was announced from All Nippon Airways.

As for cause the effective expiration of the encoding certification which is set to the terminal certification management server.Beginning when introducing the terminal certification management server into 2005 September, was the expiration date which is set.

As for beginning the expiration date which is set in 2005 September

2005 September terminal certification management the server introduction (as for encoding certification function not to use,)
The encoding certification functional expiration date while they are 3 years later of initializing
In “2008 September 14th 1:44 AM it is set”

2007 September “skip service” (the reservation customer the za just does the card with the embarkation mouth not to stop in counter, embarkation procedure completion,) it adjusts to introduction, for private information protection of the renewal occupant it starts using encoding certification function by the terminal

1:44 AM encoding certification functional expiration date is cut off
When All Nippon Airways and the cooperation which is the nationwide 51 airport 4 it tries to start 1,556 terminals it cannot clear the certification of encoding processing and it becomes a state where it cannot start with error

There is report that 3:45 AM the terminal does not start at Kitakyushu airports

morning3when50minute make sure there is nothing wrong with the network side and the center of kitakyushu airport

morning4when28minute local maintenance personnel for repair

morning5when31minute there are similar reports from haneda airport, found that the failure has occurred in the national airport

ana is in the analogy that there is a problem to date have been processing between the server that you are terminal and terminal management, given the interim procedure to check the date to stop functioning.

the recovered sequentially at each airport terminal, including the route from haneda airport63flights canceled, 358came out to the flight delay.
all day to make ends meet without knowing it of the aircraft, such as canceled, that the airport chaos. there is also that weekend, but was supported by such employees to take proceedings by hand, returns near ana counters filled with people waiting for the boarding. 7had an impact on everyone.

2time of initial mistake

this system failure why did prevent in. it is the first motion was close.

when there was contact with the terminal does not start in the kitakyushu airport, has confirmed there is nothing wrong with the network between the center of tokyo and kitakyushu airport first. up to this point was duly. because there was no abnormality, determines that there is a cause of kitakyushu airport terminal, will ask the repair and maintenance of local personnel.

at this time, contact to other airports, will that can determine if a trouble overall local trouble why even check if a similar event occurs or not launch the terminal.

valuable to pursue the cause of the true2that time will earn. eventually, was not able to grasp the magnitude of the trouble until there is a report from haneda airport.

the root cause is miscommunication

the root cause is miscommunication

when you introduce a terminal management server authentication, the initial configuration3leave the expiration date was still years later, because it was originally that of authentication and encryption feature is not used., there is no way this.

determines that the problem is to use encrypted authentication feature2007years9is the support of the month. person in charge of design personnel and terminal management server according to the ana terminal authentication2007years9expiration date at the time of mon1was recognized not only the year. meeting of the two documents, expiration date of this topic seems to have it.

the problem is from here, was convinced of design personnel and terminal personnel will update the management server terminal authentication. i it was not communicated properly.

said plan, was confirmed check it out that it is not going to. there is a word transfer, convey and that reach and is a distinction between. to report to work, put a report to the boss on the desk of said do not you think, and.

the same is true when working out the instructions to subordinates. not only send e-mail, it is essential to verify whether the questions that came face to face. in this has been reached will be.

in the case of this, had been recognized but each other, without confirmation, could not be transmitted as a result. from ana very basic mistake has been announced.

to prevent recurrence

system development and process improvement measures to prevent recurrence has been announced from ana.
in addition to, confirm that there is no system that uses cryptographic authentication of the terminal management system (performed)
-extension of the expiry date of cryptographic authentication of the terminal management system (performed)
inspection system for the expiration date of the features in
· promotion of standardization in the system development process
establish a review system by a third party outside of the system development process

system failure this time was not a bug in the system. system failure could have prevented if we even check the expiration. because it is not a thing like me and warned to expire just as anti-virus software, if you do not tightly manage, quite unaware.

measures promotion of standardization in the system development process there are, confirmation of the expiration of the function you should have joined the new check sheet. of the development process in the development system, not just manufacturing visualization do, need a way to go in the process crafted in quality.

ana reservation and ticketing system trouble

in measures to prevent recurrence of this when, same time promotion of standardization in the system development process it was working there is a, 2007years9of the month skip service with the introduction was not utilized.

due to the expense of the audience is approximately canceled2billion will be, miscommunication that has gone expired with high.
