Investigating
At the moment our Event Servers are returning higher than usual 502 responses. We are investigating the issue and will post an update after 15 minutes or earlier if we identify the issue. We recommend retrying failed events until you receive a 200 response from Amplitude. Amplitude SDKs already take care of the retry logic.
