it appears its 1/2 coming in and then split into two 3/4, one going to the toilet and one to the outside faucet.
is this bad news?
Yes. This is just the opposite of the way it should be. Your supply lines should start out large and become smaller (e.g. 3/4″ going to 1/2″ branches). You will need to replace the 1/2″ line with 3/4″. This will probably benefit the water flow to other fixtures in your house. BTW, how large is the water main coming into your house? It ought to be larger than 1/2″…if not, you should have that replaced as well.
