The main web server will be undergoing a minor upgrade on Tuesday, February 24th at 5:00 pm to allow for some case insensitivity in the URLs. Service could be intermittent during this window. TSO does not anticipate any problems from this change, but some pages could experience unforeseen complications. TSO will be monitoring the website closely over the next few weeks in order to correct any problems or revert to the case sensitive model if necessary.
