Accidentally dropping the production database doesn’t seem that big of deal in comparison to killing the electricity in two countries.

unless it is database of russian oligarchys bank accounts in vietnam where they hidden their stolen money. XD

Unfortunately these things usually take months, being done at the speed of bureaucracy.

It's not the speed of bureaucracy, it's the speed of doing a good job

Things like Air Crash investigations don't take a year because of paperwork FFS. Investigating things takes immense time.

Who would be responsible for writing the postmortem? Are they required to?

I think it's ENTSO-E, here's their most recent report into an incident on 21 June 2024: https://www.entsoe.eu/publications/system-operations-reports...

For that incident, an expert panel was set up in July, the interim report was published in November, and the final report in Feburary 2025: so it'll take a few months.

I would expect the Spanish parliament to have some means of summoning an explanation, via its local regulator and grid authority. https://www.ree.es/en/about-us/regulatory-framework

Not required, but engineers tend to enjoy this sort of thing. Also, since it affected some 60 million people and EU-wide grid interconnects, someone will have to explain what happened.

Definitely looking forward to this postmortem.
