codesign fails due to timestamp issue - server probably down

I'm signing using "Developer ID Application" and it suddenly started failing due to the following reason A timestamp was expected but was not found.. from the logs it looks like a failure to connect Apple's dedicated server. Perhaps there's a way to verify this theory, or get another timestamp server to be set in --timestamp option?

thanks
