🚨Airbus has just confirmed to me that this issue does indeed relate to single-event upsets, also known as bit flips🚨
This is pretty massive.
There is scant detail so far but they say "solar radiation" has caused problems for some aircraft.
This *could* be related to single-event upsets, where cosmic rays trigger computer errors. I've asked Airbus if they can share more detail.

Last Friday night and Saturday morning, Monmouthshire was hit by devastating floods. Monmouth’s high street, a place that I’ve barely known wet before, became a high roaring river (see the pictures of how it lies normally, as it did on Thursday, with the flooded Waitrose high above).

These sorts of major outages are thankfully very rare - but they do highlight how interconnected services now are.
As we saw last year with Crowdstrike, companies that have thought about resilience will be back up and running quickly. Others may take some time.
