In november 2017 I (
Hive account@scipio) had published the initial "invention post" regarding the UserAuthority algorithm, after which about a half year later I got into contact with 
Hive account@holger80 to develop the UA code. End 2018 the 
Hive account@steem-ua account & algorithmic curation began, which became, immediately after its launch, the fastest growing account in terms of individual delegators. Hive account@holger80 has always been in control of & running the Hive account@steem-ua servers.
I haven't had contact with Hive account@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 Hive account@steem-ua servers going (it has been algorithmically voting continuously, despite me not getting in touch with Hive account@holger80. In case of questions from the community, I (Hive account@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 Hive account@holger80, in a final attempt to notify him about Hive and possible server re-configurations regarding Hive account@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 Hive account@steem-ua servers stopped functioning, both on the Steem and the Hive blockchain.
So herewith I announce that Hive account@steem-ua has stopped, because I don't have access to said servers myself, and I haven't heard from Hive account@holger80.
Please UN-DELEGATE to Hive account@steem-ua, bot on Hive and on the Steem blockchain. I want to personally thank everybody that has been delegating to Hive account@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 Hive account@holger80's well-known GitHub-repository, and in case you'd also like to continue with the Hive account@steem-ua account name, then you can contact me (Hive account@scipio) on Discord.
I hope everybody understands, I don't want to cause any confusion.
Thanks you, and Steem + Hive/Buzz on!
Kinds regards Hive account@scipio
