In November, a thread in this community explained how Zilla might be down when someone looked but up again when the person they mentioned it to checks it... and then back down :)
By "down" I mean I'm seeing: Software error: data/versioncache did not return a true value at globals.pl line 361. For help, please send mail to the webmaster (webmaster at zilla.livejournal.org), giving this error message and the time and date of the error.
I got that message March 2nd and emailed the address, I didn't know if the addy was monitored but it never bounced. Zilla worked again the next day at least. Same message on March 8th / today.
