Throttling and whitelisting

[Matija]

Is there some way to 'whitelist' my local app that is accessing GAE app?

Every last day of month we are doing backup and few seconds after process startup our local app faces extreme throttling. F4 instance and nobody else is using it at that time. Am I missing something ?

Again, nobody ???

It's not clear (to me at least) what you are asking. 

What "throttling" are you talking about?

That screenshot just shows a bunch of requests. Looks pretty normal from 'the outside' - we dont have the context of knowing what you think is wrong with it. 

... try rewriting the question assuming anyone trying to answer, knows absolutely nothing about your app, situation, setup, and the background - so you need to explain pretty much everything. In fact this just so happens to probably be true. 

Again, nobody ???

Ok. We have locally java server that connects to GAE and requests some data. In the beginning of this process, GAE responses very quickly and first 10, 20, maybe 50 requests are returned very fast and everything is as expected. But suddenly (after very nice beginning) it starts to throttle our requests to let's say 1 request/sec - 1 request/2 sec although there is no other load.

I think that there is some DDoS protection GAE feature or something like that but there is no official response.

Google’s Edge will deny you if you start doing too many requests that look the same.  You get a pop up fill out a captcha life is happy for 24 hours.  You have to work pretty hard to get these, but I have seen it.

YOUR ISP may throttle you if you look like you are trying to DDoS a site. I get this a LOT more than I hit Google’s edge.  If your response is slow, and the bit speed slows down. It is your ISP.  If the 5XX Error page is not a Google Error, it is your ISP.

Yes. There was problem with our QoS settings. This 'backup' server is actually used almost always internally, and this monthly backup is, let's say, only time that it needs to connect to outside world. So our firewall and vpn gateway had low QoS settings for this server. So thanks for hint. There was no problem on GAE or ISP side.

My only concern is that there was no response from GAE team to resolve sooner this mystery.

Thank you, Matija.
