This is a pattern one might see if there were a secret, rolling disclosure of some exceptionally-bad software vulnerability, I'd think. Or same of some kind of serious but limited malware infection across devices of a certain class that sees some use at any major tech company. If you also didn't want to clue anyone else (any other governments) in that you'd found something (in either case), you might fix the problem this way. Though at that point it might be easier to just manufacture some really bad "routing issue" and have everyone fix it at once, under cover of the network problem.
