#Sci-hub status: Online, but note new domains (as of Apr 22, 2016) .
From Sci-Hub: URGENT! The blocking of Sci-Hub domains is ongoing. It is very likely that soon sci-hub.io address will stop working. Yes, we have another addresses to move on. But there is a better solution. You can simply specify 22.214.171.124 as one of your DNS servers in your computer network settings. Any domain will work then regardless of any blocking. How to do this? There is an instruction available for OpenDNS, however you can use it for Sci-Hub too. Just type in 126.96.36.199 instead of 188.8.131.52. At the university, you can also ask computer network administrators to configure this DNS server for Sci-Hub domains. This operation will revive even for old addresses: sci-hub.org, sci-hub.club and others. Please share this information to all interested parties, and Best regards!
