Jun <var data-var='date'>22</var>, <var data-var='time'>20:56</var> UTC Resolved - Between approximately 19:11 and 19:23 UTC, a subset of Check API requests returned 5xx errors, which also intermittently impacted Console and Components. The errors occurred because a routine deployment introduced a new data value that application instances still running the previous version did not yet recognize; while the rollout was in progress, requests served by those older instances failed. Error rates returned to normal at 19:23 UTC once the deployment fully completed and all traffic was handled by the updated version. We are implementing safeguards, including updated data-migration and deployment practices plus additional automated review checks, to prevent similar issues in the future. No customer action is required, and the issue did not affect payment or payroll processing. Jun <var data-var='date'>22</var>, <var data-var='time'>19:29</var> UTC Monitoring - The system has recovered and is now operating normally. The issue was transient and related to an in-progress deployment. We are continuing to monitor the system closely and are conducting a root cause analysis to better understand the issue and prevent similar occurrences in the future. Jun <var data-var='date'>22</var>, <var data-var='time'>19:24</var> UTC Investigating - We have identified an increased number of 5xx errors in Check API, which is also impacting Console usage. Investigation is in progress.

We will provide another update at 11:45am ET. Jun <var data-var='date'>18</var>, <var data-var='time'>14:38</var> UTC Investigating - Delayed employee payments were identified this morning and are under active investigation. Many payments are processing, though arriving later than expected, and the total number of outstanding payments is actively decreasing. Work with our banking partner is ongoing, and we expect to work through the remainder of the day to ensure all affected payments are processed. Note: This only impacts payments that were funded and scheduled to land today. Please confirm any reported late payments are included in a payroll dated for today with no funding issues before escalating. No support outreach is needed to ensure payments are included in our efforts.

Jun <var data-var='date'> 6</var>, <var data-var='time'>20:56</var> UTC Identified - Update: We have confirmed the root cause and are now applying a database fix. We are rolling the change through sandbox first before applying to production. Due to the size of the change, we are revising our estimated time to resolution to several hours. We will continue to provide updates as the fix progresses. Payroll preview and approval remain impacted across all payroll types in production. These endpoints will be unavailable in sandbox during application of our database fix. Other endpoints are not affected. Jun <var data-var='date'> 6</var>, <var data-var='time'>20:41</var> UTC Investigating - We are investigating an issue impacting payroll preview and approval. Requests to preview or approve payrolls are returning errors. This affects all payroll types. Other endpoints are not impacted. Our team has identified a database capacity issue as the root cause and is implementing a permanent fix. Estimated time to resolution: within 90 minutes.

Payroll preview and approval errors

May <var data-var='date'>27</var>, <var data-var='time'>00:04</var> UTC Resolved - On the evening of Tuesday, May 26, 2026, a code change caused a subset of API key requests to incorrectly return 403 Forbidden. We detected the issue after a partner report, reverted the change, and restored service within approximately 5 hours. We are deeply sorry for the disruption. This explains what happened and what we are doing to prevent recurrence. Impact The issue was live from Tuesday, May 26 at 8:04 PM ET to Wednesday, May 27 at 1:27 AM ET, a window of 5 hours and 23 minutes. During that time, API requests that create or update resources (POST and PATCH) returned 403 Forbidden for a subset of partners: partners who had their API key associated with a Console user of the roles standard or cost owner. Most partners were not affected. Read traffic (GET) and the underlying data were not affected; no records were created, modified, or lost as a result of this bug, and approved payrolls and scheduled payments continued to process normally. Root cause We deployed an authorization refactoring on our write endpoints. The change contained a bug that caused the new check to incorrectly reject legitimate write requests for some partners if their API key was tied to a Console user with a role of either standard or cost owner. These unintended errors were mixed with legitimately rejected traffic, which affected our detection time. The change was reverted. No further action is required from partners, and any request that failed with a 403 during the window can be viewed in API Logs and safely retried. What we are doing differently First, we will reintroduce the change behind a safer rollout, re-landing the additional write-path authorization check with additional automated tests for this API key provisioning setup and in more incremental stages. Second, we will tighten our deploy guardrails by restricting changes affecting authentication or authorization to adjusted hours, along with implementing more robust post-deploy monitoring for faster response. If you believe you saw a related issue outside the window above, or have questions about this incident, please reach out to us and reference this note.

Apr <var data-var='date'>28</var>, <var data-var='time'>16:01</var> UTC Resolved - 4/28 — Resolution Update and RCA Impact and duration: From approximately 1:05 AM PT to 1:44 AM PT on Tuesday, April 28 (~40 minutes), API endpoints across the platform returned elevated error rates and Console pages were intermittently unavailable. Health checks returned to green at 1:44 AM PT and the system has been stable since. What happened: Two scheduled background jobs ran simultaneously in the early-morning window and pushed our cache layer past its memory limit. Once the cache filled, normal cache writes began failing globally, which surfaced as the broad API degradation. Today's root cause is distinct from the SEV-2 on Friday, 4/24, which was driven by an inbound webhook volume spike from a banking partner. We traced today's failures directly to cache memory pressure, not webhook volume. Going forward: We are taking immediate steps to prevent recurrence, including reducing the load these scheduled jobs place on the cache layer and improving how the system handles cache pressure so it degrades gracefully rather than producing errors. We are also strengthening monitoring on cache health and related signals so this class of issue is caught before it impacts API availability. Apr <var data-var='date'>28</var>, <var data-var='time'>08:45</var> UTC Monitoring - The system is recovering. We are actively monitoring to ensure it remains recovered. Root cause analysis to follow. Apr <var data-var='date'>28</var>, <var data-var='time'>08:37</var> UTC Investigating - We've identified an event impacting AVI availability and performance inconsistency. Investigation in progress.

Degraded API Availability + Performance

Apr <var data-var='date'>24</var>, <var data-var='time'>21:10</var> UTC Resolved - 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. Apr <var data-var='date'>24</var>, <var data-var='time'>13:36</var> UTC Update - System is recovering. We are still investigating this issue to understand root cause and therefore prevent recurrence, as well as assessing potential impact. Apr <var data-var='date'>24</var>, <var data-var='time'>13:33</var> UTC Investigating - We identified spikes in API latency and errors. Investigation in progress.

Spikes in Check API Latency and Errors

Apr <var data-var='date'> 9</var>, <var data-var='time'>16:45</var> UTC Resolved - 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. Apr <var data-var='date'> 9</var>, <var data-var='time'>13:42</var> UTC Monitoring - A fix has been implemented and we are actively monitoring our systems. Apr <var data-var='date'> 9</var>, <var data-var='time'>13:26</var> UTC Update - We are continuing to investigate this issue.

Service degradation impacting Production and Sandbox

Mar <var data-var='date'> 3</var>, <var data-var='time'>20:25</var> UTC Resolved - 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. Mar <var data-var='date'> 3</var>, <var data-var='time'>12:52</var> UTC Monitoring - 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. Mar <var data-var='date'> 3</var>, <var data-var='time'>11:41</var> UTC Investigating - 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.
