Friday evening we started getting intermittent SSL errors when connecting to the API servers.  We use the active merchant library(http://activemerchant.org/) from ruby in two different apps and those both had the same issue.  About 1/11 connections that were attempted threw this error:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

This was consistent between both applications, and neither got any updates related to this on Friday.  What I've seen online is that people who previously got this error got it because some of the servers were not sending along the intermediate certificate.  That would be consistent with what I am seeing.  When I tested with ssl_strict=false this morning the errors stopped, but that is not a solution I want to depend on.

Any thoughts?
