Well, I guess their host doesn’t work weekends so lets hope it will be back up on Monday.

In the meanwhile, you will probably also get a timeout error message when updating your projects which have the Propel repository linked with svn:externals. Here’s a list of the different options you have:

• The easiest: don’t update the external libraries. On Windows, select “Update to revision…” in the TortoiseSVN right-click menu and check “Omit externals” instead of performing a normal “SVN Update”. Since you’ve probably linked to a tag it doesn’t need updating anyway (unless someone linked to a new version).
• Create your own repository with the files you still have in your working copy: inside the external libraries folder, select “Export” in the TortoiseSVN menu and export to a new folder which you can then import into a new repository. That new repository can then be used as an svn:externals link.
• Include the Propel files from option 2 inside your project instead of linking to them. But this takes away the flexibility svn:externals provides, so it is not preferable.

Luckily, most SVN servers have a good up-time record.
