Hi,
I was just writing a post about this myself. I'm having the same problem.
I already surrounded all my cache.get() calls with a try/catch block so the
app can proceed normally (without the benefit of memcached though).
I thought it was related to the Appengine maintenance, but I'm seeing this
for already approximately 4 hours.
Caused by: com.google.apphosting.api.ApiProxy$CapabilityDisabledException:
The API call memcache.Get() is temporarily unavailable.
