At the moment my main board supplier seems to be back in business, and I am getting shipments again. At work, most of our suppliers in China are responding again and shipments have basically resumed with very few exceptions. So any supply-chain hiccups from China will be already resolving. Since most businesses should have planned for the down-time of Chinese New Year, I doubt we'll see anything more than a brief hiccup at most.
I'm mainly just seeing US sources right now that are notifying of potential interruptions for electronics components, but no actual supply issues. We seem to be getting all our orders on schedule at the moment.
