In november 2017 I (
@scipio) had published the initial "invention post" regarding the UserAuthority algorithm, after which about a half year later I got into contact with 
@holger80 to develop the UA code. End 2018 the 
@steem-ua account & algorithmic curation began, which became, immediately after its launch, the fastest growing account in terms of individual delegators. @holger80 has always been in control of & running the @steem-ua servers.
I haven't had contact with @holger80 for quite some time, although I've regularly tried to contact him via Discord DMs, but no reply came back, although he kept the @steem-ua servers going (it has been algorithmically voting continuously, despite me not getting in touch with @holger80. In case of questions from the community, I (@scipio) have been trying to help everybody as good as I could, despite not having access to said servers myself.
In light of the recent events of the Hive fork, I have tried to again get into touch with @holger80, in a final attempt to notify him about Hive and possible server re-configurations regarding @steem-ua. I still hadn't heard back from him.
The past few days, since the Hive fork is active, I saw (of course) that the @steem-ua servers stopped functioning, both on the Steem and the Hive blockchain.
So herewith I announce that @steem-ua has stopped, because I don't have access to said servers myself, and I haven't heard from @holger80.
Please UN-DELEGATE to @steem-ua, bot on Hive and on the Steem blockchain. I want to personally thank everybody that has been delegating to @steem-ua until now / or has been at some point in the past.
In case anybody else likes to continue with the service, you can find (parts of) the open source code of UA in @holger80's well-known GitHub-repository, and in case you'd also like to continue with the @steem-ua account name, then you can contact me (@scipio) on Discord.
I hope everybody understands, I don't want to cause any confusion.
Thanks you, and Steem + Hive/Buzz on!
Kinds regards @scipio
