Comment (by lumpysimon):

 I've started seeing this a lot recently (possibly only since 4.4.2
 upgrade? Although I'm not certain of that), across several sites on
 different servers, all WordPress 4.4.2, either PHP 5.6 or 7.0.1, both live
 and on localhost.

 Here are a couple of example outputs from Query Monitor in case it's
 helpful. The first one is retrieving data from twitter.com, the second
 from maps.googleapis.com
