Narrative:

At cruise altitude received a message from dispatch inquiring if 'everything was ok with engines?' we responded everything was normal and that all engine parameters indicated normal. However; we requested that dispatch 'keep an eye on us.' next message from dispatch was to 'go ahead and divert.' in addition; we were given approval by dispatch to go ahead and land over weight. We verified with dispatch and diverted. We received landing data for the over weight landing via ACARS. We then told flight attendants to cease service and prepare cabin for diversion. We then informed passengers we were diverting for precautionary reasons. We were met by maintenance. We were informed by maintenance that in-flight data transmitted to dispatch showed dual engine failure at 5;500 MSL when we were already at cruise.
