Naver's ad operations team has announced scheduled maintenance for ADVoost Shopping campaigns, catalogue sales campaigns and ADVoost creatives, for service stabilisation.
Schedule
| Window | Date and time (KST) |
|---|
| First | Monday 27 July 2026, 21:00–23:00 |
| Second | Tuesday 28 July 2026, 21:00–23:00 |
| Third | Thursday 30 July 2026, 21:00–23:00 |
All three run for two hours from 21:00.
What works and what does not
Continues: ad delivery keeps running.
Suspended:
- Product information updates (product name, price, sale status and similar)
- Creative registration and editing
- Editing ad product names and images on the catalogue management page
One more caveat: after maintenance completes, product information re-syncing can take up to three hours. A window ending at 23:00 may not be fully reflected until 02:00.
If you would rather not serve during maintenance
Naver outlined two options:
- Use Detailed schedule > Serve by day and time in the advertiser centre to exclude the window
- Switch the campaign OFF
Naver also advises against editing during the maintenance windows.
Practical checklist
- Confirm no price changes or promotion launches are scheduled for the nights of 27, 28 or 30 July
- Check that month-end creative swaps do not collide with the windows
- Leave slack for the three-hour re-sync delay
