We have noticed that for some Tag Managers the DNS name look-up for "www.mytaglist.com" can take very long, sometimes over 10 seconds. During the lookup, the tag manager orange up arrow will stay lit and tag manager cannot respond to user commands. We just made a change in the server side (that retroactively becomes effective on all existing long range tag managers with rev>5) to configure your Tag Managers to only do the name look-up once at power on, not each time sending new tag update. This should result in significant reduction in the time the orange up arrow light stays on, and hence a much more responsive tag manager, especially when the number of tags is large and auto-update interval is short.

You don't need to do anything for this change to be applied to your Tag Manager, but a power cycle will not hurt to make sure this change has been applied.
