this has started happening quite frequently since a week or so. It is far from a major problem, but more of a annoyance.
Sometime, when I go on a webpage, the page seems to load as plain HTML. Then, after a refresh, the rest of the page loads.
Why is that ? Any idea on what could cause this problem ? See screenshots.
Windows 7 64 bits, using Chrome, up to date.
EDIT: Thanks for the help and suggestions. To be more specific, this is happening at work. My connection is filtered, but that's all I know.
