The H.15 site has links to the original September 17, 2001, release as well as
to the revised releases for that date and for September 24.
Data for most of the interest rates reported in the H.15 release of
September 17, 2001, were missing for September 11-13 because of
inactive markets or delays in data processing arising from the
disasters of September 11.
On September 25 the Treasury released the data that had been
missing for September 13 regarding the constant maturity interest
rates on Treasury securities and the secondary rates on bills. On
October 1, 2001, the Federal Reserve issued a revised version of the
H.15 release of September 17 to show the September 13 values of those
series and the correspondingly updated values of the averages for the
week ending September 14; also on October 1, 2001, the Federal Reserve
issued a revised version of the September 24 release to show the new
values of the averages for the week ending September 14.
