@robi My experience corroborates yours - I actually contacted SSDNodes earlier this week, wanting to lock in prices now for some servers due to renew later this year in the fall.
They replied that there would be no increase in prices on the renewal until then. Of course no guarantee and things can change between now and then but for now, I am inclined to leave them the benefit of the doubt.
In parallel, the quotes/offers I am getting for physical server hardware have a 3-days lifetime max, due to availability of parts and prices fluctuation. Forget about comparing offers from multiple suppliers in this situation: one needs a short decision-making path to make these effective in these conditions.
