Low results in Cambridge masters - Getting into PhDs

I'm wondering about my chances at getting into PhD programmes. I did very well at undergrad, and got full funding for a masters at Cambridge. Unfortunately, had a bit of a rough year at Cambridge and my results are relatively low (averaging at 64).
I'm aware Oxbridge PhDs are out of the picture now, but I'm wondering about my chances at other universities. I'm thinking that being accepted might be doable, but getting funding might be hard. Or will my low results be taken with a bit of a grain of salt because it's from Cambridge, and because I won a Cambridge masters scholarship, etc?
Thank you for any input!
