[google-appengine] Re: Super High Latency!! many 500 response! What happen to GAE?
Hi, We are having the same problem. We have had the service down for almost 20minutes. We also use Django 1.1 and I understand than importing all modules might take time but it usually works in less than 500ms, and now it is producing DeadlineExceededError just in the imports, so before any query. This is really unstable. Can somebody explain us this, please?

Well, this is the third time I try to send this message. Am not feeling very lucky today :-) Our application is suffering the same problem. App Engine is not running normally today. Apart from DeadlineExceededError, we are getting this warning: Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. This warning results in an 500 error message to the user with "Error: Server Error" Someone from Google can explain this, please?

[google-appengine] Re: Super High Latency!! many 500 response! What happen to GAE?
We are also facing this problem. Too many DeadlineExceededError. We also use Django 1.1 but the same app usually loads within 500ms, and today we have been down for about 20 minutes. Now we have deployed the version precompiling the app (just changing app.yaml and deploying) and so far we haven't found any DeadlineExceededError but still a bunch of 500 error responses, which in the logs appear as warnings: "Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team." Something is not working fine today definitively. Someone from Google can give us an explanation please?

Same things you say are happening to us.

We are still facing as many DeadlineExceededError as the past days, but now it is happening while sending emails: DeadlineExceededError: The API call mail.Send() took too long to respond and was cancelled So the app loads, it works and it gets this exception just trying to send a single email to a single recipient.

[google-appengine] Re: Frequent deadline exceeded errors.
Hi,
Our app (id=mavencharts) was down last night from 8:04PM (Pacific
time) to 8:51PM, this is almost 1 hour. We just got error 500 trying
to load the home page (google.appengine.runtime.DeadlineExceededError
and also the warning saying.. "After handling this request..." which
is also error code 500). According to appstats, our app makes 7
queries to datastore to load the home and it usually loads within
300ms. When memcache is available the home page makes just 1 query to
datastore.
We use GAE Django-helper with django 1.1
Since last september the 13th, system is unreliable and we are really
worried because things are not getting better.
Google engineers tell us they know there is a problem but nothing
more. If Google think this situation is going to last, it would be
great to tell us, so that we can consider moving to another cloud
system, rather than just wait.
Thanks

[google-appengine] Re: Still getting errors sending mail
However the user just told us the he has got the email this time. Does it always tries to resend the email after the failure? Can we make sure every time Send is cancelled, it is processed at some point later?

[google-appengine] Re: Frequent deadline exceeded errors.
This answer does not help Ikai. We are facing this problem even in
urls that just load and render a simple form. Just rendering html.
They even don't access Datastore and still we get
DeadelineExceededError. In the last 2 days we have had about 30 falls.
Sometimes the problem even does not reach the logs, we just see the
message in the screen and nothing goes to the logs.
On the other hand, the Datastore is terribly slow and we all know
that, so Google can't tell us our methods should run under 1000ms.
Because the technology you provide is so slow!. This is not serious.
Again, is there anything we can make to fix this situation?
Thanks

Is there a way to optimize Gae-Django-Helper load time? Thanks On 26 oct, 00:37, Geoffrey Spear wrote: > On Oct 25, 12:37 pm, Carlos Ble wrote: > > > This answer does not help Ikai.

[google-appengine] Re: How to mock or instantiate App Engine Entity when unit testing
App Engine is so great that you can not write unit tests using entities even if you don't persist them. Just calling the constructor of an entity makes all the datastore stuff load which is slow. You do not want your unit test to take 1 minute to run, do you? What we have done to be able to write unit tests is to not create objects directly but use a factory. So we have an EntitiesFactory which give us objects which are not actual entities but have the same properties. Apart from the benefit of running tests fast and isolated (because they are not real entities they can't alter database), we get a new layer that makes it easy to migrate to other persistence mechanisms.
