'mtr' is a TUI traceroute with a bunch of extra features (which I occasionally find more of) - in it's default mode it shows all the network hops between you and your destination - and shows packet loss on each link, which is great for finding who is to blame for a *partially* dodgy connection. Hitting 'Z' shows you the ASN for each hop, which lets you find who owns it; Hitting D gets a scrolling display so you can see where momentary blips happen.
