Server 10 - thank you for your patience while we addressed the issue with Guild War today. We restarted the server at 5:30 PM CT and matchmaking has been done successfully.
You are now in the sabotage phase. The battle phase will begin at the regular time tomorrow (11 AM CT), so you will have a shorted sabotage phase.
If you did not receive your end of war rewards, or you have any further issues, please contact support so we can review your logs.
