[google-appengine] Re: latency started spiking up dramatically today

['Nick (Cloud Platform Support)' via Google App Engine]

Hey Wenzhe, 

We have no incidents reported on the Cloud Status Dashboard 
 for Datastore as of this moment. 
Sometimes performance may degrade for a short period of time dependent on 
Data-Center conditions. You should check out SLA on Datastore 
 and consider implementing some 
exponential back-off logic in your code to handle the possibility of 
deadline exceeded errors. We have a document on this topic titled "Dealing 
with DeadlineExceededErrors 
".

I'll check to see if I can find any other explanation and will report back 
to this thread. 

Cheers,

Nick

Hey Wenzhe,

Apologies for not including this in my last message, as I had believed your 
original message included the necessary information. Can you email me your 
project ID directly at pay...@google.com? I'll be glad to take a look for 
you after that. Is this still occurring, by the way?

Regards,

Nick
