IT: We are migrating old internal file page to new internal file page, but don’t worry, we’ll be locking the old page!
Me: Takes note of this, waits for announcement that migration is done.
IT on Monday: New pages live, old pages locked, update your bookmarks!
Me: Dutifully updates bookmarks, starts using new pages, where all the files have been successfully migrated.
Team on other side of world: Continues to use and update old pages, everything is out of sync because IT did not in fact lock down all the old pages, and team on other side of world did not update the bookmarks.
Me: Sends slightly seething messages to IT to lock the damn pages down and other side of world team to STOP USING THE OLD PAGES.
It’s going to be one of those days.
