If it's at work only that's probably an issue with the Firewall at you office, in particular if they cache things and don't refresh the cache very often. Thus the cache right now may be corrupted and will clear itself out over a day or two. This assuming it isn't normal of course. Doing a Shift-F5 to force a full refresh of the web page can sometimes resolve that as well, but that's only if the corporate firewall will pass the force refresh along.
Right now at work I'm still getting 3-4 second loads. It's about 6-7 seconds on my cell, majority of that time loading my images from Google Drive.
