Sussex County officials are alerting residents about an upcoming multi-day shutdown of critical computer systems that will disrupt many county services.
County administrators announced they will take their financial and permitting systems offline for upgrades aimed at boosting performance, security, and reliability. The extensive maintenance work will affect operations across most county departments.
The system shutdown is scheduled to begin Sunday, April 19, 2026 at 8:00 PM and continue through Wednesday, April 22, 2026 at 4:30 PM.
During the nearly four-day maintenance window, residents will lose access to several essential services including all payment processing capabilities, permit applications and related transactions, and the county’s self-service website.
County officials are urging residents to prepare for the service interruption and handle any urgent business before the shutdown begins. Those who have appointments with county departments during the maintenance period should contact their specific department or staff member directly to discuss alternative arrangements.
The county expressed regret for any inconvenience the extended downtime may cause while emphasizing the improvements will ultimately benefit residents through better system performance.
