My internet speed has seemed to slow down since thanksgiving?

Could be any number of reasons depending your connection type and speed you've signed up for. If you have an ADSL connection your speed should be consistent all the time. If you have a cable internet connection then your speed can fluctuate depending on the number of people in your geographical area using the internet at one time (since you share a connection). Your best bet would be to phone your service provider and inquire to them.
