Service issues, Las Vegas

Hello!  Is anyone having issues with their internet coming and going in Las Vegas?  It seems to happen randomly (twice this morning).  I will be online and then suddenly is shows no connection.  My Network connection shows full strength but indicates there is not internet connection.  Generally if I just wait a few moments (2-10) it will come back on its own, but not always.  I would say this has been happening since mid November.  Any ideas?
