What an irony that the Deutsche Bahn caused an outage of Deutsche Lufthansa. And Deutsche Lufthansa now tries to shift domestic flights to Deutsche Bahn[0] (see also for general advice/help). And who got recently a Star Alliance member? Deutsche Bahn. And who has experience with interrupted cut-off fibers[1]? Deutsche Bahn!<p>*Please*<p>All critical system shall be working autonomous. Cache flight/passenger data locally at airport for next weeks. Servers are for synchronizing, not for keeping your data away. With a local cache you can keep going for some weeks, adding/changing bookings will be harder but you can remain in the air. That is pretty complicated and requires more work but is important. Git or IMAP are examples how it should be.<p>Outages will happen and will keep happening and when the get more seldom, the will become more serious because it will hit inexperienced staff. Especially British Airways is known for issues[2][3].<p>[0] <a href="https://www.lufthansa.com/xx/en/flight-information.html" rel="nofollow">https://www.lufthansa.com/xx/en/flight-information.html</a><p>[1] <a href="https://www.heise.de/news/Sabotage-bei-der-Bahn-Viele-vertrauliche-Infos-sind-offen-zugaenglich-7307277.html" rel="nofollow">https://www.heise.de/news/Sabotage-bei-der-Bahn-Viele-vertra...</a><p>[2] <a href="https://thepointsguy.co.uk/2017/09/amadeus-network-issue-causes-delays/" rel="nofollow">https://thepointsguy.co.uk/2017/09/amadeus-network-issue-cau...</a><p>[3] <a href="https://www.datacenterdynamics.com/en/news/british-airways-experiences-major-outage-says-it-is-not-a-cyberattack/" rel="nofollow">https://www.datacenterdynamics.com/en/news/british-airways-e...</a><p>PS: Deutsche Lufthansa is known for reliable transport.

“ Lufthansa said construction work on a rail line in Frankfurt was to blame for the massive IT failure,. ”<p>No, Lufthansa not having sufficient resilience was to blame.
Interesting, most of the Nord-West area of Frankfurt was affected, residential cable internet failed but LTE/5G network of Deutsche Telekom didn't function as well.<p>edit: related tweet from Deutsche Telekom<p><a href="https://twitter.com/deutschetelekom/status/1625824840924950528" rel="nofollow">https://twitter.com/deutschetelekom/status/16258248409249505...</a>
Everything fails all the time. The fiber cut was not responsible for this. Lufthansa having woefully inadequate resiliency plans in place with their infrastructure is to blame.<p>This is 100% on poor management practices by Lufthansa, but of course they’re going to point the press to that shiny object over there in the form of a fiber cut. The press, as usual, took the bait.
There was a fiber cut last year near Chicago. It was near a railroad so a bunch of authorizations were required and it took about three days to complete the work. My parents live in a rural area that has fiber but didn't have internet because the local ISP didn't have any redundancy.<p>We switched from microwave antenna which has its own issues to fiber and my dad is thinking, "Well, you said this would be better." You can blame the local ISP, but am I wrong to think that it's hard for a rural ISP providing fiber to afford redundancy?
Crazy that an airline that is very used to the need for double- and triple-redundancy in the aircraft it flies fails to have any sort of connectivity backup for it's ground systems.
How is this possible? Presumably whichever datacenter it was hosted in, would have multiple fiber lines connecting to it? Or am I just spoiled by the major cloud providers?
