Complete LH group meltdown
"Deutsche Lufthansa AG grounded all of its flights on Wednesday after damage to a set of Deutsche Telekom broadband cables caused widespread IT problems" (link - behind paywall),
If true (ie the root cause, the disruption is very real) it is inexcusable. |
Pretty bad mess at FRA right now. Flights get diverted elsewhere as the airport is topped off with aircraft after nothing is departing. Mind you, this Friday there are big airport strikes in Germany anyway.

Workers managed to drill into a big fiber trunk 5m under ground near a railroad. Repair ongoing since Tuesday night.

Single point of failure, oh dear !

Sounds very British Airways !

As a telecoms guy It is almost beyond belief that all LHs IT could be taken out by one cable cut and on a rail track right of way where it is well known there are always going to be telecom cables ..
Its the airline industry for gods sake redundancy is built into every aspecyt of airliners but it seems not in IT systems. The CEO of the LH Group should be fired for this |

A person in that position would not normally be expected to know the full down 'n dirty technical minutiae of their system, rather they would rely upon advice they receive from company and external experts. If it transpired they knew about weaknesses in the system, were advised to address these but did nothing, then perhaps they should consider moving on. Otherwise, assuming they're an effective CEO, why not allow them the opportunity to sort the issue out? To put it another way; should a pilot be automatically 'fired' because an engineer did something that broke their 'plane? FP. |
The Piper will have to be paid.
No doubt a serious cost saving measure that turned around and bit them. Single point of failure cannot be tolerated in a failover strategy. Chief Information Officers and Financial Officers would not have adopted this strategy without the full knowledge of the CEO. There will be no hiding place. IG |

IG There is plenty of things I would fire the CEO for (e.g. closing LH Flighttraining down or the downward spiral of T&C for LH Group employees), but this is not one of them. What this really highlights, is how the (EU driven) shift to privatization of crucial infrastructure allows for these weak points to develop. |

It happened at Newark
Quite a while ago a pile driving crew was driving piles for a new garage at Newark.
They hit a concrete conduit that was not supposed to be there. It was a glancing blow. So they moved over and tried again,. This time they penetrated the conduit and hit the main power line to various parts of the airport , including the control tower and Customs in Terminal B. For added measure the back up power line was in the same conduit bank and it was hit as well. ! Nothing moved for about 6 hours and all the inbound international arrivals had to wait for customs to get power back. Seems the control tower had a back up gen set so they were OK. |
Idiot proofing infrastructure is not easy and expensive. Mainly due to the inventiveness of the idiots.
|
Don’t big companies usually have a CIO (Chief IT Officer) who can be fired for those cases? That said, Lufty probably just paid a lot of money to Telekom to get a redundant fibre connection and Telekom simply put all four fibers in the same conduit below that railway line.
The bigger problem is probably that nobody knows whats down there until you dig into it, since records are only kept within one company. In Berlin they just built the foundation for a new high rise building and afterwards discovered that they nearly destroyed the tunnel of an active underground line which now has to be repaired, stopping traffic in there for months, which is still better than nearly burying a whole commuter train in concrete. |
I am (constantly) amazed by the calls for firing people without any further information on cause or processes.
Just cause should be applied everywhere, not just in the cockpit. Somebody made a mistake, let them figure it out, learn from it and than see if somebody is to blame and in what measures. |
Replace CEO in all contexts with Captain. Reads a bit differently right?

Exactly the same thing occurred 45 yaers ago in my old ( major) Control centre. A worker using a backhoe dig and cut a bunch of cables just outside the centre , severing all telephone and radar lines ( that were all underground at the time ) Lessons were larned to have multiple access, etc.. but one of the root cause still rermains today : sub contracting basic work to the lowest bidder. In our case the guy operating backhoe was not one the regular workers who had a briefing on the cables layout , but the digging crew that morning were hired on the day to do some basic earth removal and they were not made aware of the exact position and sensivity of the cables.
I would not be surprised if the same happenned in Frankfurt yesterday with Deuche Bahn ( the railway company that was contracting the work that cut the cable), How many sub contractors down the line ? As to the resposnibily of Lufhansa, of course not their direct fault as the incident occured quite far away from the airport, but relying on a single source of communications to function, probably is. |

Separacy and diversity of networks is critical. In a development at locations such as an airport, the incremental costs are negligible compared to the cost of failure. You can plan as much as you like but Murphy is always waiting in the wings. One memorable event involved a Big Telecom company who excavated a duct under a rugby pitch using a horizontal borer. The machine was programmed to dig deeper than other infrastructure which was marked accurately on the diagrams. Nobody noticed that to improve drainage, the height of the pitch had been increased. Ouch ! Another event in Glasgow city centre involved a water main. The excavations did not touch the pipe however it had corroded to the point where the weight of the earth above it was holding it together. The dig reduced the weight and the whole pipe let go in a spectacular fashion. |
Most companies of LH size work extremely hard to ensure their networks have adequate diversity.
This often means literlaly going out and walking the paths of critical cables to ensure they reallyare seeprated when they enter your properties and not two cables in one duct.. All kinds of checking for common points of failure are routinely undertaken for mission critical enterprises . Telecoms plant is often owned or used by more than one company and so buying from company A doesnt mean they use different networks from company B . In this case it is unthinkable that they serve sucha critical facility with just one cable . The reason I said the CEO should get the chop is because he has created or tolerated an obviously slack cunture and attude when it comes to resilience as IT is critical to all major airline ops.. He gets a big bonus when they make a lot of money but he does little or none of the work to do that himself. . In this case of course LH shouldnt run their own telcoms network but theyare a big enought company in Germnay to get T Systems and other suppliers to do exactly what they want . This is big screw up so someonebig has to be resopnsible |
