Ontraport had 9 outages in the last 2 years totaling 180h 41m of downtime — averaging 0.4 incidents per month.
There were 9 Ontraport outages since May 28, 2025 totaling 180h 41m of downtime. Each is summarised below — incident details, duration, and resolution information.
We are currently investigating an issue with delayed emails.
Issue has been resolved.
Investigating an issue where lp and app are down
We are continuing to investigate this issue.
Looks like a another DDOS event. Looking to block malicious traffic
This incident has been resolved.
We are currently investigating a possible latency/traffic-loss issue.
We are continuing to investigate this issue.
We are continuing to investigate this issue.
We have identified the core of the issue (DDoS) and are working with the carrier/provider to get a proper mitigation in place. Unfortunately, it appears that the providers automatic DDoS mitigation mechanisms are extremely aggressive and are blocking far more than the abusive traffic. We are currently working to identify a solution.
We are continuing to work on mechanisms to restore impacted services.
A fix has been implemented and we are monitoring the results.
We are still monitoring and mitigating the DDoS. Services remain operational, but some latency may still be present.
This incident has been resolved.
We are currently working to address an issue where pages may not be serving properly due to high volumes of abusive traffic.
We've implemented some changes to handle the abusive traffic and services appear normal. We will continue to monitor to ensure it doesn't begin again.
It appears there were two concurrent issues happening: 1. an influx of abusive traffic (mitigated) 2. Cloudflare is having service issues which are returning HTTP 500 responses (the primary issue) We will continue to monitor.
We are still waiting for official confirmation from Cloudflare that the issue has been resolved on their end, however, we have not seen significant traffic issues for some time now and it appears that nearly all traffic is operational. We will update again when Cloudflare confirms a permanent resolution.
Cloudflare has indicated that the issue is resolved; while this may resurface, we have not seen any impact for roughly 2 hours.
We are experiencing rDNS failures related to a 3rd party and are actively working toward a resolution. This affects a small amount of traffic and would look like latency in delivery, or possible failure to deliver over time, for affected accounts. Most accounts are not affected by this issue. As this is the second time in a short time span, we are moving traffic (where possible) to other pathways while waiting for a more permanent solution.
We are still waiting for the 3rd party to resolve their failed DNS configuration. Efforts to move affected accounts off of the impacted IPs is continuing.
rDNS resolution appears to be functioning normally; we will be monitoring this to ensure that the resolution holds. It may take another 12 hours for DNS to fully propagate but the majority of impacted IPs are delivering email normally.
Restored DNS has held for roughly 24 hours. Closing issue.
Our Edge Mailer Server hosting company had a unscheduled issue with their virtual machines. We're currently working with them to bring back our mailing IPs.
Server back in place. Staying around to monitor for a little bit
One of our primary email delivery edge datacenters is experiencing issues. As such, emails will likely experience delays. Currently, no emails are being lost, and are residing in our our egress queue.
We are still awaiting resolution from the datacenter.
Most services have been restored; we are working to restore the lagging services.
All issues have been resolved.
App Is not responding quickly. Think may be related to some traffic anomoly.
Was a DDOS attack from some source. Mitigated and should be good
We are currently fixing an outage that impacts HTTPS certificates for various types of web pages.
Services have been restored. We are going to be observing and monitoring this to ensure it's fully functional.
All impacted services appear fully functional and are operating normally. The underlying cause was a cache server stall which prevented properly loading HTTPS certificates for a brief time. We will be fully investigating the cause, and implementing some changes to this part of the infrastructure to help prevent this issue from occurring in the future.
