Some of the key tool's which I use on a daily basis (and their workarounds) no longer work.
The tool I use the most of any is the autofill for PMID and ISBN's. The one in the edit box has not worked for some time and the backup http://diberri.crabdance.com/cgi-bin/templatefiller/index.cgi? stopped working today. The second backup still works a bit thankfully https://toolserver.org/~holek/cite-gen/index.php
Another great tool is the dashboard. Its toolserver account has expired. http://wikidashboard.appspot.com/enwiki/wiki/Obesity I find this strange that if a users account has expired all the tools stop working. This would be like if I stopped editing Wikipedia for a couple of months than all my contributions would be deleted.
So the question is should the WMF be helping keep some of these tools up and running? Many of us long term editors have come to heavily rely on them.
