I think you’re misreading. Even the 6 month thread was based on invalid assumptions of $0 collocation fees. Add in even cheap collocation fees and it’s pushed out even further
That’s not really a nit pick when the claims were based on impossible math. It’s more of a Motte and Bailey where they come in with a “couple of months” claim that sounds awesome on the surface but then falls back to a completely different number if anyone looks at the details.
Let’s not forget that if even three engineers are working on this migration for only a week your cost is now 10’s of thousands for this couple hundred euros cost saving.
(assuming avg all-in engineer costs in europe)
It makes no sense to optimise cost for infrastructure mostly, it does make sense to make it faster, since almost all your spend is on engineers.
Spending thousands to save hundreds is not a healthy business.
