Which London line is the most unreliable?
How often each line has actually failed over the last thirty days, counting unplanned disruption only. Transport for London publishes the present; this is the part nobody keeps.

Every line below is ranked by how long it spent disrupted over the last thirty days. Planned engineering work is excluded: a line closed on Sundays for upgrades is not an unreliable line, and counting scheduled closures as failures would make this table worthless.

How this is counted
We ask Transport for London’s open API what every line is doing, and write down the answer whenever it changes. A spell of disruption begins when a line drops below Good Service and ends when it comes back, so its length is measured rather than estimated.
Two things are deliberately excluded. Planned engineering work, which TfL marks separately and which says nothing about reliability. And any status whose validity window has not opened yet — a closure announced for next weekend is not today’s disruption.
These totals are ours, not TfL’s. The underlying data is Transport for London’s own open data, but no official version of this table exists, because the history it needs is not published by anybody.
