We were having a record breaking heat wave in the UK, we joked that see even Jenkins can't cope with the heat all builds are failing It was not uncommon to get transient failures so no one looked into it, it was too hot, in the UK we are not used to dealing with that. Eventually someone did look into it, there was some little used functionality in our platform which queried a weather API, someone had written a unit test that used the real live API and set the expected temperature value to be lower than the record high temperature in London, so our pipelines really had been broken by the hot weather.
