I have been using this site for a 2-3 years now to perform a up/down load check about once a month to make sure that my T1 service is on the ball. It as almost always has shown up/down at around 1.44
For the last 2 months my upload speed has only been showing about.833 and down remains at 1.44. I have had my system checked by my provider and now have also checked it myself with 8 other sites and have found my speed is not the problem but that this site is no longer has an accurate on upload test.
