Maybe some routing on the internet got cleaned up?
You can always do this on windows in your command window:
tracert winnipesaukee.com
Or use an online tool such as:
http://www.monitis.com/traceroute/
And see if there is a slow route somewhere.
If you become familiar with the normal routing (and timing) you can know when something is out of whack or has changed.
Or you can also use online pageload speed measuring tools:

have fun!
