Is email forwarding broken?

None of my emails are being forwarded to my other email address today.  Turned on/off the forwarding, retyped forward address and everything.  Had to turn on saving a copy of them to Comcast's web email because otherwise they are getting lost in the nothing of the internet.  Forwarding has worked fine for years prior to this.  Tested sending directly to that other address and it is fine on that end.  Something is seriously wrong with Comcast's forwarder all of the sudden and I can only hope it gets looked at.
