The log of events in that document is absolutely hilarious/pitiful. It’s like something lifted directly from an episode of In The Thick Of It.

A honest-to-goodness proper fucking omnishambles.

11:52 - senior OBR and Treasury officials telephoned each other to discuss the breach. These Treasury officials made OBR staff aware of the URL leading to the PDF of the EFO that was accessible.

11:53 - OBR staff and the web developer attempted to pull the PDF from the website, and also to pull the entire website (e.g. via password protection), but struggled to do so initially due to the website being overloaded with traffic.

11:58 - an email was received to the OBR press inbox from a Reuters journalist confirming that Reuters had published details of the EFO and asking for comment.

12:07 - the EFO PDF was renamed by the web developer.

12:07 - the EFO PDF appeared on the Internet Archive. This means it was, at that precise time, visible entirely generally on the open internet via search engines. It is assumed that this happened very briefly in the rush to remove it.
