Cvsdude will be doing some migration soon. Cvsdude provides the SVN repository for The Gamebook Engine, and the latest Beta release. They will be doing this migration sometime between July 28 and Aug 4. They do not expect downtime to exceed 15 mins. I will be keeping an eye on SVN and the downloads throughout the migration week, to make sure there aren’t any problems.
This website is not related, and will not have any problems. The wiki will be fine. The Stable releases, and the Lone Wolf: Flight From the Dark gamebook are hosted elsewhere. Only SVN and latest Beta archives might be affected.
