So, when I gain a link I always check to see if the page that is linking is in the Google cache. I've noticed recently that more and more pages are actually not showing up in Google's cache, yet still appear in search results. I did read an article from someone whoo works at Google a few weeks back that there is sometimes an error with the cache and occasionally the cache will not display. This week, my own website isn't showing up in the cache yet I'm still ranking in SERP's. I'm not worried about it, mostly whitehat, but has there been any indication that Google are phasing out the ability to check cache's of websites?
