Since wikitech has a less then stellar track record of uptime, we've setup a nightly generated static copy of the archive at
There is a cron set under the user cron that runs once nightly to populate the tree. If you need to run the generation manually then try the following
php /srv/org/wikimedia/wikitech/extensions/DumpHTML/dumpHTML.php wikitech -d /srv/org/wikimedia/wikitech-static/ --image-snapshot --force-copy
Which will copy over all images and text to the destination directory.
