Is amazon having routing issues in my region? How do I contact amazons peering team?

My region: south east Europe.

It worked nice until yesterday.

We have direct peering with amazon in our DC and in an IX and it worked great until yesterday.

Traffic going from us to AWS is going nicely where it should, trough our peering. However, all or most traffic goingn from AWS to us is going from Frankfurt to roundabout ways, several dosens of hops, to Romania, Bulgaria and then to us. Trough one of our uplinks, and it seems to pick the worst ones :)

We have tried emailing amazon to peering-to@amazon.com but in 6 hours we got no response yet. Is there any other better way to contact their peering or network team?

Rumor is that another local ISP has similar issues with Amazon right now.
