I too am getting this error, unfortunately this is the only result on the matter.
I have tried all the usual suspects and it has persisted over the past two days - is anyone else currently experiencing this error?
EDIT: I decided to try and test if it was a bandwidth issue, so I rooted around in my router and optimised everything and it seemed to have done the trick. Seemingly the issue stems from my ISP.
I really do wish they had a big book o' error codes..
