ProRail power failure was in datacenter British Telecom – Update




The original reason for the large signaling and points failure in and around Utrecht, lay in a computer center of British Telecom in Nieuwegein. An independent party is now doing research there, made ProRail Tuesday.

ProRails computer systems and networks for train driving around Utrecht located at British Telecom, as saying ProRail. The data center meets all kinds of security requirements. Thus, such as food and air conditioning redundant and who satisfy the so-called Tier 3, the highest international standard for data centers.

ProRail wanted last weekend to expand the power for its systems and took therefor in consultation with British Telecom to provision the computer center under the microscope. The company, which is the only user of the power supply, therefore took his own words precautions. After a short outage would therefore no consequences arise.

Everything seemed to go so well, until Monday morning ‘unexpected’ one of the computer systems of the signaling Utrecht failed. It went according to ProRail to a computer that was connected to the system last weekend fell short in Nieuwegein. This system switched to a backup system, which took over the job, but the data server could not load.

ProRail says that the failure defects were created in the hardware of both the data server and the redundant computers. More the company does not know yet. ProRail late than do self-proclaimed independent party investigation into the failure to “learn from this failure and in the future to prevent this.”

“The first conclusion is that the overall system including the redundancy have a ‘tick’ got over the weekend because of the momentary outages probably arose from a disturbance in the power supply. It is also clear that the ProRail systems have equipment that impact flow changes must occur, but it seems that this has worked enough. Research must still confirm “explains ProRail. All the damage has been repaired.

ProRail says despite a substantial investment ICT failures can never be avoided completely. The company has since 2007 more than 100 million euros invested in improvements to the traffic control. This concerns, among other things, upgrading computer centers and dual computer systems and networks. According to the company would thus have been at least eighty percent less interference. “These failures range from a broken computer on the post with one delayed train to result in a major failure in the systems with much inconvenience for travelers.”

Update, Wednesday 12:00 ProRail stressed that the power failure is not the fault of British Telecom. That debt was initially been aroused in this piece.
