I assume you (@erengy) are aware of it, but every service under Tools -> External Links
have died / is inaccessible.
Hummingboard - When you give an account name it just keeps loading. The site is running fine, but I assuming something broke in the API, and hence it isn't working properly.
I assume @wopian 's service works out to be a good alternative instead? (I haven't used Hummingboard before so I'm not exactly certain of what that does)
MALGraph has discontinued it operations.
Mahou Showtime Schedule seems to be down. I get the error that it is unable to connect to the server. (This as far as I know could be a temporary issue, but it feels like too much of a coincidence)
fansubwiki.com/ leads me to a cloud-flare security check. On completion though I get a 403 Access Forbidden error
You don't have permission to access /
on this server.
Additionally, a 403 Forbidden
error was encountered while trying to use an ErrorDocument to handle the request.
Was checking for alternatives and it seems fansub.d-addicts.com/ is also broken (site times out). There is fansub.dramawiki and fansubdb.com/wiki/ but I don't know how good they are.
