Is anyone else noticing the internet not working like it used to? Do we blame Google?

OK, the internet is not the most robust thing in the world, but I’ve been using it for many years and have come to expect certain responses from pages, certain errors, similar patterns when something is going wrong. Now I’m finding everything I knew is different. New errors don’t fit the pattern. What I’m interested in is whether anyone else has noticed this? As for what it means… Fluther guidelines say healthy debate should be discouraged, so yes/no answers only people!
