I'm seeing the same behavior too.
The message isn't helpful:
"
Probably Reason
    BitcoinWisdom is temporary down
    Domain is not bitcoinwisdom.com
    Network issue
"

None of that is actionable. E.g. I don't know what the domain problem is supposed to be.

I'm getting it from multiple PCs, devices that used to work until yesterday.

Hey bitcoinwisdom folks, please fix your broken site!
