Noticed lots of RR loading issues yesterday for sure -- maps, forums. I had other indicators of connectivity issues over the last 24+ hours as well to include no connectivity at all this morning (more than just RR). My service has been restored but now seems to be capped at a lower speed than I should have.
Not sure how much is my local provider vs. something farther upstream but I've submitted a report to the provider.
BTW - I just ran a check and I am running Chrome 61.0.3163.100 but when I did the check, Chrome seems to be pulling in an update now - more to come....
EDIT: after the Chrome update, I am now running 62.0.3202.62 -- maps, etc. loading fine (it seems) before and after the update - at least this morning / right now.
