Ninety Minutes, No Phones, One Cut Cable. And 197 Breaches Caused By Daylight Saving.

LONDON, United Kingdom — At 08:00 on a Tuesday in July, a security officer took this newspaper's telephone, tied a paper tag to it marked 11, and put it in the eleventh hole of a wooden box.

The box is not a safe. It is a box. Sixteen holes, a hinged lid, a brass hook, in use since 2011.

He then closed the door of Room 4.06 from the outside and stood in front of it for ninety minutes.

That is a statistics lock-up: sixteen desks, a clock, a monthly figure that moves the price of money, and a door held shut from the corridor side until 09:30.

We asked whether we could describe the room. We were told yes, on one condition — that we read the department's incident log as well.

Sixteen desks and one blanked faceplate

The desks are ordinary desks. Eight along each long wall, numbered on tape. There is a kettle.

The clock is radio-controlled. It is the only object in Room 4.06 that receives a signal from outside it.

By desk nine there is a data outlet with a blank plastic plate screwed over the hole. Somebody lifted a floor tile for us: four power runs, and one data run terminating in nothing. On the floor below, in riser cupboard 3.11, there is a taped cable end with a printed label reading DECOMMISSIONED and a date in November 2019.

A box, a door, a clock, and a socket that stopped being a socket seven years ago.

What an embargo actually is

It is not a law. Nobody in that room has signed anything with a penalty clause. Pre-release access is a list — forty-one organisations, 108 named individuals — and the only sanction the department holds is removal from the list.

That is the whole mechanism. You get the number ninety minutes early so that what you publish at 09:30 is not nonsense. If you publish early, you can be taken off the list.

Two hundred and fourteen rows

We asked for the register in writing and had it in nineteen days: every detected pre-release publication from April 2021 to March 2026, 214 rows, one column withheld.

One hundred and ninety-seven of the 214 are automated scheduling faults. Not a person deciding to publish early. A content management system firing an item at the time it was told to fire it, in the wrong offset.

Seventeen were human. Seven were lines read out on air between forty and ninety seconds early. Four were notes sent to clients before the window opened. Three were social posts queued by hand. Two were regional print runs distributed early. One was a spreadsheet mailed to a list at 09:29.

The last Sunday in March

The 197 are not spread evenly. One hundred and twenty-one of them fall in the five working days after the last Sunday in March, which is the morning the United Kingdom moves to British Summer Time.

A scheduler holding an item at 09:30 UTC releases it at 10:30 once the clocks go forward, which is late and harmless. A scheduler holding it at 09:30 local, on a server whose clock has not been told, releases it at 08:30. That is an hour early, into a live market, and it is a breach.

Another thirty-one cluster in the three weeks each spring when the United States has changed and Britain has not, and the Atlantic gap is four hours instead of five. A release engineer reproduced both faults for us on a test system in under ten minutes.

The remaining forty-five are ordinary misconfiguration, scattered through the year.

Three sanctions

In five years the department applied a sanction three times.

Twice to Frayne Bulk Index of Hull: four people, a dry-bulk freight letter, no lawyer. Suspended six months in November 2022, removed permanently in February 2025, both times for a client note sent inside the window.

The other two client-note breaches in the same period were sent by organisations employing more than four hundred people each. Both were written to. Neither was suspended, and the department declines to name them.

The third sanction was applied to nobody. In March 2024 an account belonging to another government department published a derived chart at 09:26. The outcome cell reads: Referred. No action available.

What the room is for

The room works. It has held for ninety minutes a month since 2011 and the man who stands in front of the door says nobody has ever tried it.

Everything around the room is a spreadsheet, a clock-change bug, and a judgement about who can be removed from a list without it becoming a problem. The sealed part is the part that never fails, which may be why it is the only part anybody photographs.

Rosalind Teversham-Achebe's reply is below, in full, and it takes the word "cut" out of our headline with a maintenance ticket. It also contains a sentence we would not have got any other way: she has asked four times for a lockable cabinet to replace the wooden box, and been refused four times, and the cabinet costs about nine hundred pounds.
