Hello,
is there any problem with Mikrotik production? I am trying to find CCR2004-16G-2S+ for sale in eshops in central europe, and there are exact ZERO pcs available, some eshops stating that production has ended. Is it some kind of temporary shortage? I am planning home reconstruction - to move all networking devices into rack, picked this exact tik to be fit for my needs, but now I am struggling to get one. Should I look for something else or wait? How long?

Join the club. A lot of electronic equipment/assemblies is still on shortage by various problems.

I am waiting for RB5009 for over 6 months.
It "should" come back available in some months, I hope.

Covid is still raging like crazy in China and Taiwan. Where do you think most chip manufacturers or assembly plants are located ?
Where do you think they put their focus with scarce resources they have ? On the high-end margin generating products.

Simple fact:
Look at the car industry and how they did in 2022 (preliminary results, applicable for most brands). Lower sales numbers (a LOT lower) yet HUGE profits.
How do you think that happened ?

That would explain the lack of availability projecting Feb for hapax3.
