I have a set of servers that are currently using a single domain name with multiple DNS A records to round robin load balance. I have ported my service to run on the Google App Engine and I would like to add the google hosted service to the round robin list on the domain name. However GAE apps do not get assigned a static IP address. All I get from google is a domain name for the service.
The organization I work for requires that the service not be hosted by a single company to provide a sufficient level of fail over redundancy. I would like to host part of this service on GAE but I don't see any way to do it and still have it accessed by the same domain name as the rest of the servers.
