This should be a reminder to everyone that ALL leagues that use any type of electronic lineup submission should have something in their rulebook to accomodate this type of situation. We have a separate message board (what are the odds of them both going down?) where you can post your lineup for the commish to edit later in the event of technical issues.
It is also helpful if the commish has a phone with an answering machine as an emergency...once we had a guy who's service went out during a storm and he called the commish from his cell to submit his lineup.
In extenuating circumstances, our commish also has the authority to rule on a lineup submission after kickoff. We've never had such a request be approved, but at least it is in the rules.
