Thanks. I did manage to contact Len - nice that he has an email address that is not linked to the site.
This is what he said:
Network Solutions took it offline because some robot is using the Google Search page to send out a
great number of messages. It needs a "captcha" or the like and I am paying
them for the programming change. Then their legal department has to okay
going back up. I find it all very frustrating since there are searches on
lots of websites without captcha.
Hope that all of this can be archived. One would hope that there is someone or some group that will be interested in all the information that is stored there, about El Toro fight, of course, but also about the continuing story of aviation in SoCal.
