Since I get connectivity failures in the last months for almost every notary in https://github.com/moxie0/Convergence/wiki/Notaries, I gave up using Convergence Addon temporarily. Only two old style notaries seem to respond to my browsers questions.
Additionally, adding most of the listed notaries fails with "Unknown notary bundle version". I'm using Convergence 0.09 with FF 17.07 or 17.01.
Is this a usual overload issue or something special with my software?
