I use GAE for a 24/7 support portal. People enter support issues and the portal will notify technician by email on their BlackBerry (yes I know, not Android...).
The problem is that every night Google mail infrastructure (mail API) seems to have delivery problems around 00h00 EST. Most delivery are delayed by an hour, sometimes two.. Since we have an SLA to respond to support issues within 30 minutes, that's a big no go. Here's included are the delivered email headers (I changed the email address for privacy concerns) of one of the emails that was delayed. We can see that the email was received in Google infrastructure 21h34 PDT, but left only at 23h18 PDT. I suspect that the problem is with the bridgehead servers from GAE, since emails sent to gmail don't experience the same delay. Anybody experienced this?
