In other articles about that I read that this is related to a software component called "System T7". There was a very similar incident in April related to that

T7 isn't just a component, it's the name for the whole trading platform for Deutsche Borse's markets (and it's generally very good)

  It is pretty much a step above all the other exchanges in Europe. Asking around here, nobody is reporting any issues though, so it is possible only some stocks are affected.

    Xetra, Eurex and their T7 users Wiener Borse, Budapest Stock Exchange, and some others were halted most of the morning - luckily the stocks can be traded elsewhere, but the derivatives not so much.

      yes, I just saw the discussions in the support chat.

    I wouldn't say that, and I've interfaced with most of them it's better than Euronext Optiq, but that's about it

The T7 trading system is used by the following exchanges for derivatives trading: Eurex, European Energy Exchange (EEX), Powernext. Source: https://www.eurexchange.com/exchange-en/technology/t7 https://www.eurexchange.com/exchange-en/technology/t7 Are those down as well?

  Yes, they were at least partly :- https://www.eurexchange.com/exchange-en/trading/production-newsboard https://www.eurexchange.com/exchange-en/trading/production-n... (but not Powernext - they are still on a different platform )

    According to the comment IDs, you beat me to the punch by 4 comments. Looks like i need to upgrade my HN commenting stack to use an FPGA ...

      Or do as the "Flash Boys": use a microwave link with direct path, and post from the network card, avoiding the kernel stack... I've enjoy your humorous reference.

  Eurex was down: https://www.eurexchange.com/exchange-en/trading/production-newsboard/Emergency-Information-T7-not-available-2090256 https://www.eurexchange.com/exchange-en/trading/production-n...

I'm not sure about the particular component but Xetra/Eurex indeed went down in April. Same pattern as today: it went down around the opening hours and got fixed around lunch time. They have some structural problems that have likely been left unsolved.
