4 line cards in and the cabinet has been waiting for a 5th since early February. Dates offered for the new install went 5th March, 12th March, 26th March and now 16th April.
Given the enormous scrap that was had to get the thing built out in the first place I can't say this makes me happy.
This previously unviable cabinet will have spent over half its life since initial go-live unavailable due to lack of capacity.
