I don't know much about servers performances. But I doubt this kind of survey could render any useful information. The panel isn't representative of anything. Maybe those who choose to respond are rather happy, or unhappy. Who knows. If by chance, the panel would be representative, the survey would mesure an unknowned mix of feeling and expectations from people having no comparison point. Why using this method of customers survey ? If you want to know how speed or reliables hosting providers are, install sites on their servers and test them. Technical mesures would be real information.
