I posted my first post inside hour from noticing this, 18 hours ago right now.

From what I can see, it's waiting/transferring something from google.com and gstatic.com (I think, that one stays only momentarily) for minute or so.

It also goes for slot1.images1.wikia.nocookie.com (bit unsure, only stays for a short time) before starting to wait for google, if that helps anything.
