iTunes’ Ping Facebook Application Killed

When I signed onto iTunes Ping this morning (HK time) I was able to connect my account to my Facebook account to locate my Facebook friends who are already on Ping.

Later on in the morning I start to encounter problems with the Facebook connection. It first thinks that I am no longer connected, then when I try to reconnect it has trouble reaching Facebook.

After a few more attempts the Facebook Connect button on the Ping Home page in iTunes disappeared.

Did Apple kill the Ping Facebook application? Or did Facebook killed it because it stressed Facebook’s API infrastructure too much?
