Note that overreliance on EF C alerts does have some pitfalls. My recent SWU from a few weeks ago cleared at 1-2 days prior to departure without getting a EF alert. In fact, no alert was ever sent up to departure.
Not saying that alerts shouldn't be set up, but continuing to monitor inventory is still important.
Are you saying that C space was showing but the alert never fired or just that your upgrade cleared? I imagine the two databases are not instantly sync’d so your SWU clearing probably happened before the next EF refresh, so it never had the chance to see the newly available inventory.
