Q:

PayPal SDK Sandbox mode returns response with the wrong links

I'm using PayPal .NET SDK for REST API v1.5 and I've always been able to successfully use the sandbox mode for testing. Since this afternoon create payment API (creating them with authorize intent) in sandbox mode gives me a response with the wrong links, more specifically:
1. GET, SELF, https://127.0.0.1/v1/payments/payment/PAY-3J041487P5058351GKYHKEDQ
2. REDIRECT, AUTHORIZE, https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-2W7266730F1412848
3. POST, EXECUTE, https://127.0.0.1/v1/payments/payment/PAY-3J041487P5058351GKYHKEDQ/execute

I've always got back the sandbox links for the 3 of them whilst now, as you can see, 2 of them point to localhost and one (the one that I actually need to authorize the payment) points to Live paypal.
When using Live mode instead of sandbox everything works fine.
Anyone else getting this ? Could it be just a temporary problem with the sandbox environment? or could it depend on the SDK?
Thanks in advance

A:

This is a problem with the sandbox environment. PayPal is aware of the issue and is working to resolve it. I will follow up here, when I have more information.  
Edit: The issue should now be resolved as of Oct 5 at 11:35 AM PDT
