MSN AdCenter Upgrading June 8th

I received the following notice of changes to the AdCenter at MSN coming on June 8th:

I am pleased to inform you about an upcoming Microsoft adCenter upgrade that offers new features to improve your online advertising experience.

Some upgrade highlights:

• Schedule and run reports in the background while you are working within adCenter
• API upgrades:
o API customers will now have access to enhanced reporting features.
o Upgraded API code will coexist with the previous version of the code to improve transition.

Your keywords and ads will remain live during the upgrade
The adCenter upgrade should be complete on June 8 between 4 P.M. and 8P.M. Pacific Time. During this period, your current keywords and ads will continue to run, however, you won’t be able to access adCenter to make changes.
