Has limited advanced warning.
Upper Deck informed me via email, their e-Pack service will go offline this morning for scheduled maintenance.
"In an effort to continually improve Upper Deck e-Pack, we periodically need to perform maintenance and upgrades to the e-Pack website. As a result, the Upper Deck e-Pack website will temporarily be unavailable on 3/7/2016 starting at 9:00am (PST). Normal service will resume shortly thereafter," Upper Deck informed me at 5:26 AM PST this morning.
A three and a half hour warning is highly professional...
