Yeah I agree you on that one. If manufacturers ask as huge prices as they currently do, the gear better be bullet proof.
If the user is left with some probability risk of gear breaking,
then that down time risk should be seen in the initial price being lower than it now is.
Canaan reported in a press release that they have received a massive order "Canaan Announces Significant Customer Order of 11,760 Bitcoin Mining Machines"
https://canaan.io/1081.html, so for their own sake they ought to have their chip sourcing strategized. Such large orders would naturally mean they should have the ability to provide replacement parts, as well. But I also wouldn't be surprised if their priorities shift from smaller/home mining operations to large scale miners. Still, they're going to need to be able to source replacement components for even bigger operations if this is the case.
Under the contract, Canaan will ship and install its A1246 ASIC AvalonMiners throughout 2021, adding a total of 1.05EH to Mawson’s global mining operations.
Considering that the 1246 has their proprietary onboard controller, and I'm guessing that a large mining operation is going to be using their own home-cooked controllers and software, this order is probably for a stripped down version?
Regardless, hopefully these components will be available quickly, as they've most likely ramped up production.
