Flight diverted due to a technical issue, how can I find out what happened?

I was on this flight and I am wondering if there is anything available online to see what actually happened? I don't think it was serious at all but would still love to know - out of curiosity. The airline hasn't shared any details, although I suspect they'd reply with _something_ if I asked nicely over email..?

Ask an airbus engineer. They might have the satcom feed for maintenance reports.
