<body> <h1>Service down forever</h1> <p>The Etherpad Lite server that used to be here has been taken down and replaced with <a href="https://etherpad.wikimedia.org/">a new one</a>. If you need to get something off of this instance urgently, please contact MHolmquist [ at ] Wikimedia [ dot ] org and explain your situation.</p> <h2>Public Service Announcement</h2> <p>In the future, if you're on a website that is a subdomain of "wmflabs.org" - like "etherpad.wmflabs.org", for example - you should absolutely avoid putting any sensitive or important information there, unless the particular site has made assurances to the contrary. Labs is mostly a place for developers and sysadmins to play around with new configurations and show off in-progress work, and it's not guaranteed to be stable. So please, don't treat it like it is!</p> </body>
