What It Means, What To Do, and Why Timing Matters
If you have a Marketo instance hosted in the US, and in San Jose specifically, then you may have seen a message in your instance pop-up:
“Critical Marketo Engage system maintenance Adobe will perform required network maintenance for Marketo Engage in the San Jose data center on May 16, 2026, to enhance reliability and scalability. During this maintenance period, all services will be unavailable between 4:00 PM and 6:00 PM UTC. “
This maintenance will involve a complete operational downtime. Adobe has used additional time to validate their approach and implement safeguards, allowing them to complete these required updates within a shorter, consolidated window. We recommend you take the following steps to mitigate any impact on your business:
- Avoid creating or updating Lead records or any processes that generate or modify Lead records.
- Do not trigger any follow-on processes during this time, as all scheduled campaigns will be paused.
- Temporarily disable active integrations that send data to or receive data from Marketo Engage.
- Do not initiate any data imports, exports, or transfers into your instance during the scheduled maintenance window.
- Avoid running major lead generation campaigns during the maintenance window to minimize impact.
- Request form submission caching: For customers using externally hosted forms, Adobe can support caching during the window. Contact Adobe Support with your Munchkin ID and relevant form IDs before May 11.
Impact on additional Marketo Engage services
Please note the following additional impact on your subscriptions:
- CRM integrations will be temporarily disabled and should resume automatically once reactivated.
- LaunchPoint services will be disabled during the maintenance window.
- Landing Pages, Forms, and Data Collection will not be available. Adobe will display a maintenance message during the downtime.
If you have questions or need assistance, contact Adobe Support via the Support portal in Admin Console or via Experience League. For real-time updates, please visit Adobe’s Status page at https://status.adobe.com and subscribe to receive the most current information directly.
Why the Timing Matters
This announcement is a fully scheduled downtime for any Adobe Marketo Engage customers with instances on the San Jose data center on 16 May 2026, between 16:00 and 18:00 UTC. While this is a much shorter window than previously planned, it still represents a total service outage.
The 16:00–18:00 UTC window means the operational impact will vary by region:
- North America: This will occur during the morning or midday on Saturday, May 16.
- EMEA: This will take place in the late afternoon or evening on Saturday, May 16.
- APAC: This will occur late Saturday night or very early Sunday morning, May 17.
Since this falls on a Saturday, many batch campaigns and launches should be mapped precisely against your campaign calendar to ensure they don’t overlap with this two-hour window. We recommend auditing Marketo for active Smart Campaigns and Programs operational in this window, local time zone.
Are you affected?
This maintenance applies specifically to the San Jose data center. To confirm if you are affected, head to Admin → My Account → Support Information. Look at the Data center field. If you see identifiers such as sj, sjx or sjrca, you must prepare for the outage. If you are hosted elsewhere (e.g., London/lon06), you are not in scope yet – subscribe to the Adobe status page for the latest migration updates.
Integrations and Data Safety
During this window, the API will not respond, and any system attempting to push or pull data will fail. This includes Salesforce, Microsoft Dynamics, webinar platforms, and middleware like Zapier.
If you do nothing, you risk failed sync attempts, partial transactions, and reconciliation work the next morning. For Salesforce users, we recommend manually disabling the sync (Admin → Salesforce → Disable Sync) and re-enabling it once Adobe confirms services are restored.
Post-maintenance plan
When the window closes at 18:00 UTC, we recommend running a series of tests:
- Re-enable CRM sync.
- Confirm LaunchPoint services have reconnected.
- Check the Notifications area for failed or paused campaigns.
- Validate critical forms and run a quick reconciliation check against CRM.

Conclusion:
A two-hour total outage might seem brief, but for a mission-critical platform like Marketo Engage, it requires surgical preparation. By auditing your San Jose-hosted instance now, disabling high-risk integrations, and coordinating with your sales and web teams, you can ensure that this “critical maintenance” remains a routine update rather than a data disaster.
Don’t leave your lead flow to chance on May 16 – mark your calendars, follow the pre-maintenance checklist, and keep a close eye on the Adobe Status page to ensure a smooth transition back to full operations.

CRM integrations (Salesforce, Microsoft Dynamics) will be disabled. It is recommended to manually disable your sync before the window begins and re-enable it once Adobe confirms services are restored to prevent sync errors.
No. Landing pages and forms will be unavailable during the window. Adobe will display a maintenance message to visitors. If you use externally hosted forms, you must contact Adobe Support by May 11 to request submission caching.
