It is not a localized issue it seems more to affect several IXs,

Internet exchanges don't route packets, they switch them.

If an IX fails, path will take a different route.

ISPs do the routing, they pick the paths.

therefore traceroutes are pretty useless.

As they show the path that you are seeing to have problems with, they are quite useful. As then somebody else could verify for you if they have the same issue or not.

It looks like some quite big player stopped transit thus causing a rerouting over less preferred links.

Again, stating "some quite big player" does not give anybody the chance to even verify if that is really affected or if it is just you.

If you would include source/dest and/or a traceroute you would be told by other people which ones and the problem could be reduced to just the the ones that do and do not work.

A simple answer like "no, I'm not aware of any problems" would have been enough :-)

As the Internet is a really big place, this is the answer you would then expect from everybody.

But hey, we are now 1:1 You're not happy with my question and I'm not happy with you answer...

You will never be happy with any question that anybody will give you as you did not provide any specifics and thus you will never get an answer to your real question.

The only answer that works is "the 'Internet' works, it is your problem"
