For further information:

html-load(dot)com, error-report(dot)com are domains owned by Ad-Shield and similar "as recovery" services that:

• inject a script into the site from its own host
• script checks if ad blocs load content or not
• if no ad content is loaded, they phone home to html-load(dot)com or a similar address (making it appear to the average user that they're some "core internet service")
• id html-load or their other domains aren't reachable (they send a keyed request so it's not as easy as having your own server respond with an empty {} script), the site will unload CSS and deliver a blocking view
