When I try to view the vote count, MSE gives an error message "Error in vote count fetch" Is there any solution? It doesn't happen all the time, but it does happen quite frequently, around 80% of the time.
I've checked the logs; for you specifically, on math.se, over the last 7 days, for that route - we have:
response | count ---------+-------- 200 | 9 404 | 30 409 | 7
which I agree is unusually biased. Checking further, all the broken ones are requests to a broken url; I am investigating where this is coming from, but can I ask what browser you are using, in case that is a factor?
