This is drying me nuts for last 5 days!!!
Out of the blue 5 days ago, SVN access from my MacBook Pro failed: I cannot access any SVN (i.e. not in our University or open source projects etc).
The error obtain when performing 'svn co', or any other svn commands is shown below. This is same message is obtained irrespective of the svn repository (i.e. it is something due to my Macbook)
svn: OPTIONS of 'http://anonsvn.internet2.edu/svn/i2mi/branches/GROUPER_1_6_BRANCH': Could not read status line: connection was closed by server (http://anonsvn.internet2.edu)
