Even if anyone wants to use Fixedfloat, it seems they are under maintenance

Of course, the same thing twice in a very short period, they would be idiots to continue working with the same software and server settings.
FixedFloat does not require users to KYC, which may be the only advantage it can attract attention and get users.
Fixedfloat is not a 100% no-KYC exchanger, they reserve the right to hold the user's funds until they receive information about the origin, while also retaining the right to forward user data to a third party.
That is certainly not the no-KYC definition.
