The top-level post uses a gift link with a view count limit. When it runs out, an archived copy of the article is available. I’ll note that the article has been substantially expanded since initial publication, and the archived copy captures the expanded version, and not the as-initially-published version.

To summarize, what’s going on is that while many nominations only require 50 votes to end debate, diplomatic posts have generally relied on unanimous consent to end debate, and Senator Brian Schatz has announced that he will not be agreeing to unanimous consent on any of them, forcing a day or two debate in order to get them confirmed. Since the US has an ambassador to almost every country in the world, debating them all means spending a year or so doing ambassadorial confirmations, which is completely impractical, and unlikely to actually happen.
