Outgoing bandwidth explosion

[n8gray]

Hi,

I've got an app that I've had running for a long time now and its
resource usage is highly predictable. The app consistently uses about
60-70MB outgoing bandwidth per day. But today the dashboard tells me
it's used over 2GB! When I look at the bytes sent/sec graph for the
last 7 days there's no difference between today and any other day. In
fact, all of my plots look typical. I tried searching my logs for
"bytes:[1-9]\d{5,10}" and got nothing -- there were no huge requests.
What's going on here??

Thanks,
-Nathan

Maybe you have user uploaded hot-linked images that are served from blobstore?

Do you have any UGC? For an evil guy there is nothing more interesting than hosting

porn images on the blazing fast GAE infrastructure with you paying for it.

I really wish one could disabling hot linking of blobstore images.

Cheers,

-Andrin

No, nothing like that. The app is a backend for an iPhone game that
doesn't use blobstore or allow uploads at all.

Nathan - I think there is some random issues going on with GAE. I'm having my front end instance hours blow up like crazy today - similar to your bandwidth. Nothing has changed in months - average usage for it was $.01/day. Now it could go to many dollars a day if I let it.
