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. Apr <var data-var='date'> 9</var>, <var data-var='time'>13:25</var> UTC Investigating - We are currently investigating this issue with the highest levels of urgency.

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.
