I've been in that scenario where for example 9 out fo 10 links are dark fibre or wavelengths but that last one is a layer 2 service form a 3rd party. In such a case you neet to drop the MTU on all links to the smallest supported value across all links. Take control of your network, don't rely on the PTMUD, set a value you know works (test every link).
