[Zope] Problem with zope.org?

Hi! I'm getting this or similar errors quite frequently these days: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /foo. Reason: Document contains no data Additionally, a 502 Bad Gateway error was encountered while trying to use an ErrorDocument to handle the request. Apache/1.3.12 Server at www.zope.org Port 80 This seems to be a problem with zope.org, not my local stuff. Cheers, Joachim.
