When I tried to download kibana 6.1.0 package for "Linux 64-bit" in official website, I've got error page.
Then, I modified above URL into https://artifacts.elastic.co/downloads/kibana/kibana-6.1.0-linux-x86_64.tar.gz, I got kibana-6.1.0-linux-x86_64.tar.gz successfully.
This issue is based on https://github.com/clear-code/statistics/issues/97 (in Japanese).
