Welcome to WebmasterWorld Guest from 22.214.171.124
Anyone shed any light on why google's cache dates are so far back?
Number of my sites aren't being cached, and doesn't seem like <major news sites> are either.
All last cached around the 14th-15th July

I'm also seeing strangely old caches of pretty much all pages, but I haven't had a chance to compare this to spidering activity yet. It seems to be a global problem of some kind anyway. It also seems to be concurrent with the cache for 'fresh' content being unavailable across the board.
A few weeks ago I had to hard code every URL on a specific site to example-example.com because Google had made duplicate pages using exampleexample.com, even though that site has never, ever used the exampleexample.com name, it having pointed at example-example.com for 10+ years.
I can find cache dates of this site for between 6-9th July STILL with exampleexample.com.
Yeah, I know, plenty of people claim to have done their work yet but never have. Is this AI at work? A bot pretending it has done work when, in fact, it has not?
Even for the aggressively-spidered sites I work with, the newest cache I get is July 18th (although the actual SERP is more recent)
Yea, that's the most recent I can find as well (and the actual SERP is about 15 hours old at the moment)
I also have this weird situation with a client site where every page on the site has a cache date of between July 10 and July 15, *except* for the home page, which hasn't been cached since June 9, for some reason. Really bizarre; I can't figure it out.
Google may be running out of storage space again and obviously the least critical storage is the cache. With no study to back this up, my guess is 99% of Google users don't use the cache unless and until a site/page goes down/is missing.
It's a huge resource burden that may not be financially justified.
In more recent times, I guess the processing power is being used for some other purpose, spidering given a lower priority for a short while.
I've written stuff about this a year or so back, but I don't remember the details now. I've learned not to stress about day-to-day fluctuations too much. If I see something that appears to be going wrong, I check for obvious technical problems with the site, then wait a week or so and see if Google reverts - they always do.
