Do you have any sort of security rules in .htaccess? A poorly thought out rule could be stripping data in certain situations. What about extra redirects? In some cases data can be dropped between redirects. The comment submission apparently worked for me, FWIW. I guess I don’t use one of those IPs or hosts.
There’s nothing wrong with WP, this is happening between form submission and your server getting the POSTed data (maybe without data). The error is thrown by your server before WP is involved because there is no data in the POST request. What we can do here to help with non-WP issues is limited. I’m inclined to think the problem is at the other end. For example, a host’s proxy server is mis-configured and is stripping POST data. Especially if all problem IPs all belong to one entity.
But even then, it must be intermittent or their users would be constantly complaining that no form submits work. Intermittent problems are notoriously difficult to troubleshoot.
