I don't do reddit much, so unless the results in google are inaccessible while the blackout is ongoing, this won't affect google's ability to serve the same results as it did last week.
Yes, the results are inaccessible during the blackout.
Not really, Google cache works.
Don't tell the PE guys about archive.org and .is, either.
Neither Google cache nor archive.org/etc. covers all pages. I've been running into that problem a fair few times
How do you get the cache?
this extension [1] can retrieve cache from various sources, including google.
