I encountered three issues with wikitech-static.wikimedia.org. Please feel free to split out into other tasks if needed.
First issue: I did this search https://encrypted.google.com/search?hl=en&q=dbreps%20tools%20wikitech and the first result was wikitech-static.wikimedia.org. Maybe this site should be marked as noindexed via HTML output or https://wikitech-static.wikimedia.org/robots.txt? Or maybe we want it indexed for backup reasons. This is unclear. I didn't notice that it was wikitech-static.wikimedia.org and not wikitech.wikimedia.org.
This confusion leads us to the second issue: I went to https://wikitech-static.wikimedia.org/wiki/Tool:Dbreps, was like "hmm, I guess I need to log in," then I went to https://wikitech-static.wikimedia.org/w/index.php?title=Special:UserLogin&returnto=Tool%3ADbreps and tried to log in. There's no warning noting that your account intentionally(?) doesn't work there.
And the third issue, after trying my password a few times, I got a stacktrace:
