Spikes in Check API Latency and Errors
Affected: APIConsole
Timeline · 3 updates
- investigating Apr 24, 2026, 01:33 PM UTC
We identified spikes in API latency and errors. Investigation in progress.
- investigating Apr 24, 2026, 01:36 PM UTC
System is recovering. We are still investigating this issue to understand root cause and therefore prevent recurrence, as well as assessing potential impact.
- resolved Apr 24, 2026, 09:10 PM UTC
This issue has been resolved. This morning Check experienced a database overload from increased webhook traffic that spiked for a a period of time on the morning of 4/24, and surfaced as high latency and error count. The team identified the issue, resolved the immediate database load concerns and restored functionality. The Check engineering team will be following up promptly with a resolution to prevent recurrence.
Service degradation impacting Production and Sandbox
Affected: APIConsoleOnboard
Timeline · 4 updates
- investigating Apr 09, 2026, 01:25 PM UTC
We are currently investigating this issue with the highest levels of urgency.
- investigating Apr 09, 2026, 01:26 PM UTC
We are continuing to investigate this issue.
- monitoring Apr 09, 2026, 01:42 PM UTC
A fix has been implemented and we are actively monitoring our systems.
- resolved Apr 09, 2026, 04:45 PM UTC
We identified and resolved the cause of elevated latency and degraded performance. A newly enabled internal process for synchronizing tax filing data generated significantly higher database load than expected, impacting API response times from ~9:15am - 9:38am ET. The feature flag has been reverted and system performance has returned to normal.
Delayed delivery of FedACH direct deposits
Affected: Payments
Timeline · 3 updates
- investigating Mar 03, 2026, 11:41 AM UTC
Overnight, the Federal Reserve reported delays processing and delivering ACH payment files through FedACH. As a result, some ACH payments (including employee direct deposits) may post later than expected today, and inbound ACH transfers/returns may also be delayed. The exact impact is not yet clear, but we believe that all direct deposits landing this morning may be impacted. We’re actively monitoring the Fed’s updates and our processing/settlement flows. Until the Federal Reserve resolves the underlying issue, there isn’t a lever we can pull to speed up delivery. We will follow-up as soon as we know more, no later than 9am ET. You can monitor the status of FedACH directly at: https://frbservices.org/app/status/outage.do?oId=145787.
- monitoring Mar 03, 2026, 12:52 PM UTC
As of 7:30am ET the FedACH system has successfully distributed all files containing Check's overnight payments to the receiving banks. These files were distributed by FedACH approximately 8 hours later than normal, at 7:30am ET today vs typical distribution at 11:30pm ET last night. This is likely to result in some banks reflecting direct deposits in recipient bank accounts later than normal. We do not have visibility or control into when each individual receiving bank will reflect these payments in the recipients' accounts as each bank individually recovers from this FedACH processing delay.
- resolved Mar 03, 2026, 08:25 PM UTC
All FedACH systems are operating normally again, as reported on the Fed's own status page here: https://www.frbservices.org/app/status/serviceStatus.do. We do not anticipate any further impact and all of our systems are operating normally. Marking this incident resolved.

Timeline · 1 update
- resolved Jan 16, 2026, 01:01 PM UTC
From about 12:15am to 1:15am ET on Feb 16, users experienced elevated latencies and HTTP 5xx responses on payroll endpoints from unexpected contention caused by a routine database migration. Service indicators returned to normal around 1:15am. We will be analyzing the event to prevent recurrences.
