There was an issue up until sometime on Sunday where the SSL cert for bugs.python.org was being rejected (it was issued by StartCom who is being distrusted). The cert got replaced but if the webhook event for your merge got rejected due to the bad cert then it would have been dropped.
Today I also spotted and fixed another issue, and verified that now the messages are showing up on bpo (see e.g. http://bugs.python.org/issue29557#msg287801). Let me know if there are other issues.

So if should be working, but you may have been caught in the SSL problem. If it persists then there's a problem in the hook-side of bugs.python.org that will need fixing.
