Alarming spike in form API failures

We're using Marketo forms across our marketing site which is hosted on wpengine. In conjunction with our Marketo forms, we use the Marketo API to write the form values to Marketo (instead of embedding the form). When the Marketo API fails to respond to our site within four seconds, we trigger a non-Marketo form that writes information directly to Salesforce instead.


Additionally, we set up a report to monitor when the Marketo API times out at four seconds. When the number of failures hits the threshold of 80 failures within one hour, an alert is triggered to our developers to investigate the incident.


Since June 1, 2019 there have been reports of frequent spikes in incidents of API failures - including a 20-hour period of consistent API failures beginning yesterday which peaks around 300 failures several times within the past day:

Our team has not deployed any changes to the site in several days, so we don't know of any changes that would impact this. The Marketo Status page does not show issues with the API service in June - does anyone know what Marketo's thresholds are for reporting an API incident and what impacts the reliability of the Marketo API? Why are we experiencing an influx in unresponsiveness?


We created a support case and we're waiting to hear back from Marketo, but I wonder if other instances are seeing similar issues.
