We target traffic two ways. One is relatively traditional dns
global load balancing, using the resolver ip. The other
method---which steers the vast majority of our traffic---vends
urls that send people to a specific PoP based on their client ip.
It appears you're having a targeting problem. Please reach out
to our NOC to get support.
