Parabolic Arc is undergoing some upgrades in order to deal with some performance issues. We are shifting it over to new server arrangement that should increase the site’s reliability.
The change has solved a problem readers were having in posting comments on the site. I apologize for the difficulties you all have been having over the last couple of weeks. It took longer than we expected to fix it.
The change over has resulted in a few issues, particularly with some of the text display. I’ll correct those as I have time.
Thank you for your patience.
