   1. Connection timeouts on hc-ping.com and healthchecks.ioPing APIDashboard

      Started: 2 Nov, 00:23 UTC

      Duration: 8 hours, 14 minutes

      We are currently investigating intermittent connection timeouts on our ping endoints (hc-ping.com) and the main website(healthchecks.io).

      Post-mortem

      Between November 1, 23:30 UTC and November 2, 1:10 UTC, Healthchecks.io (both the main website, healthchecks.io, and the ping endpoints, hc-ping.com) had intermittent connectivity issues in the form of some requests taking multiple seconds to finish, or timing out entirely. Usually, such symptoms are caused by infrastructure problems out of our control, but this time the problem was on our side: our load balancers were running out of available connection slots. Our load balancers were dealing with a flood of ping requests from a misconfigured client. The load balancers were using the “tarpit” rate-limiting to slow the client’s requests down. Unfortunately, this did not work as intended: the client did not slow down, but the load balancers were hitting their connection count limits and rejecting legitimate requests.

      We have identified and blocked network flood from a set of specific IP addresses.

      The issue is resolved.
