Hi Lawrence, most (i would say 95 %) of the backouts are for Code issues - this include bustages and test failures.
>From this Code Issues i would guess its about 2/3 for breaking tests and 1/3 Build Bustages. The other backout reasons are merge conflicts / backout requests for changes causes new regressions out of our test suites / backout requests from developers etc - In February the backout rate was (excluding the servo merge with 8315 changesets from the 13242) = 297 in 4927 changesets = ~ 6 % In January the backout rate = 302 backouts in 4121 changesets = 7 % We had a much higher backout rate in the past i think - so it stabilized now with this 6-7 % backout rate in the last months, If you think its useful, i can provide for the next monthly report a more detailed analysis like x % = backouts because builds bustages, y %= backouts for test failures etc .
