It is alarming, especially with these circumstances in the market, but fortunately, withdrawals are fully functional after an hour of maintenance and fixes.
This is typical behavior for binance. I don't love it, but alarming? I'm not sure that typical behavior that they've displayed for years is alarming other than now all withdrawals were paused simultaneously which is new, but seems rather inconsequential since anyone who trades on binance knows they pause withdrawal on coins regularly.
