https://bullseye.toolforge.org (source) uses a privately-supplied Spur API key which has now expired, preventing certain useful information from being displayed in the tool.
nb. As the original maintainer of this tool is no longer active on Wikimedia projects, the process for tool adoption is in progress.
Thinking out loud, given that iPoid-Service exists, perhaps an API call to that can be used in place of Spur directly?
I love Bullseye, but I just don't see the point of continuing to maintain it when there's a WMF-supported service that basically does the same thing. If there's something Bullseye does that IPoid doesn't, then merge it into IPoid.
And certainly, having a single service that's hitting the external Spur API will give us better ability to monitor usage, and provide performance enhancement with a cache.
Agreed — I'm hopeful that Bullseye can just use iPoid data One Day(tm), if only for things like the map/https://bullseye.toolforge.org/dartboard, but as for its utility as a WHOIS provider this is something that should (and is) being brought into mw.
