TFTP is UDP-based and is therefore routable. You can TFTP across the
Internet if you want to. The issues with TFTP have always been:

1. It's UDP-based, so lossy networks can corrupt your file transfer.
2. Inability to transfer files larger than 32 MB.
3. Fixed block size of 512 bytes means sloooow transfers.
4. No authentication at all (though admittedly that's by design).

Items 2 and 3 are not quite true anymore, as many TFTP clients and
servers now support "extended" modes with varying block sizes,
allowing for larger and faster transfers. They are not universally
supported, though.
