It may not be related to maintenance but rather to more legislation that may be imposed in many countries. I think you will face more scrutiny on privacy currency trading like Monero, Zcash and it may be unlisted from many platforms.
It is not the first time so do not worry.
I won't be surprised if a day Binance is forced to remove Monero from the listing. In Japan, most (if not all) platforms were forced to delist privacy-centric cryptocurrencies, same in South Korea.
Another example is BitBay (E.U. based by the way) that stopped to accept deposits 3 months ago and users have 2 months left to transfers their XMR out (Remember also when Coinbase removed Zcash?)
I'm sure with the time we will see more and more platforms doing it to follow the FAFT's guidelines
BitBay acted in a similar way before blocking everything and then stopping XMR etc for a week and then delist it
