问题
I was using the PalPal IPN simulator all day without problems, and at some point I got kicked out and the developer portal got upgrade.
Picking up right where I left off, I'm now receiving IPN messages from the sandbox, but attempts to validate the message return 400 Bad Request.
Now before you go saying "Oh, you just need to do HTTP/1.1 and send the Host:" field, I'm already doing that (and have been for months).
Request body:
POST /cgi-bin/webscr HTTP/1.1 Host: www.sandbox.paypal.com Content-Type: application/x-www-form-urlencoded Content-Length: 1008 Connection: Close
Response body:
HTTP/1.1 400 Bad Request Date: Sat, 09 Mar 2013 00:07:26 GMT Server: Apache X-Frame-Options: SAMEORIGIN Set-Cookie: c9MWDuvPtT9GIMyPc3jwol1VSlO=%7chl7gnTEYtJzNIfLXr3W6GtWjMBrl6ln8aFetxEss8pSDsWPDwv59RMYj7ONKH0013betZW%7cnf1wC_g4C0pER3V0XtOw2969OSDVwC24TgW3akpoK6QHdkz0_7G0YdJ9Cnjz-JKZbESVG0%7c; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: cookie_check=yes; expires=Tue, 07-Mar-2023 00:07:26 GMT; domain=.paypal.com; path=/; Secure; HttpOnly Set-Cookie: Apache=10.72.109.11.1362787646017906; path=/; expires=Mon, 02-Mar-43 00:07:26 GMT Connection: close Transfer-Encoding: chunked Content-Type: text/plain; charset=ISO-8859-1
It it just me, or is the portal broken?

You're correct. The ability to verify IPNs in sandbox is broken at the moment. We're currently working to fix the issue now and I'll be sure to update you once we have an update.
Please let me know if you are experiencing any other issues with the developer/sandbox environment and I'll be sure to follow up.
