**How was the issue detected?**
Zonos observed elevated error rates affecting Classify and Country of Origin APIs.
**What functionality was affected?**
A portion of Classify and Country of Origin inference requests did not return a valid response.
**What was the root cause?**
A firmware issue on a subset of GPU nodes caused network connectivity failures. This caused the nodes to enter an unhealthy state. Our reconnect logic did not properly remove unhealthy nodes from the pool, so they continued to receive requests.
**What was the resolution of the problem, and what steps are being taken to prevent future issues?**
Shortly after discovering the issue, we restarted nodes to resolve the connectivity issues and restore service. We then identified the reconnect logic issue, and released a fix to prevent future issues.
We have scheduled a firmware upgrade on all nodes to resolve the underlying network issue.
We have also refined our alerting to catch errors more quickly in the future.

**How was the issue detected?**
Our team was notified that Checkout domains were not being allowed as expected, leading to an immediate investigation by the engineering team.
**What functionality was affected?**
Online store settings \(allowed store domain\) were not loading properly for all stores using custom integrations. This prevented affected stores from loading checkout.

Stores relying on custom integrations could not load their checkout correctly.
**What was the resolution of the problem and steps that are being taken for continued follow-up?**
* A rollback to a previous version immediately resolved the issue.
* A new synthetic test has been implemented to ensure store settings caching is store-specific and does not mix settings between stores.
**What mitigation solutions will we put in place to prevent this issue from occurring in the future?**
* **Improved Testing:** A new synthetic test has been introduced to verify caching behavior and prevent incorrect store settings from being cached.
* **Staging Environment:** Setting up a dedicated test environment for custom integrations to catch similar issues earlier.

| **Date** | **Time** |
| --- | --- |
| November 8, 2024 | 8:50am - 10:26am MST |
### How was the issue detected?
A spike in error logs triggered an alert to our Engineering team, who responded immediately to the issue.
### What functionality was affected?
Landed Cost quotes that use our automated item classification service failed.
### What problems did this cause?
If an HS Code was not provided in the API request to Landed Cost, and the automatic classification service was enabled, then the landed cost quote would fail. When the landed cost quote fails, shoppers may not be able to place their order.
### What was the resolution of the problem and steps that are being taken for continued follow-up?
The root cause of the issue was a deployment issue with the item service used for automatic classification.
While the issue was detected immediately, resolution required rebuilding and redeploying services, which took longer than expected.
After services were rebuilt and redeployed, the system health was validated and normal operations resumed.
### What mitigation solutions will we put in place to prevent this issue from occurring in the future?
We discovered that this issue was due, in part, to a deficiency in our deployment procedures. We are working to update the procedure to prevent any future issues.
We are also creating a synthetic test in our lower environments that will catch similar issues before they can be deployed into production.

postmortem
**What products were affected and what was the impact?**
On **Saturday, October 12, 2024, at 22:30 UTC**, we experienced an outage that impacted the ability of some Shopify merchants to retrieve landed cost quotes for international orders. This outage lasted until **Sunday, October 13, 2024, at 21:33 UTC**, during which time affected merchants may have been unable to display accurate landed cost calculations to their customers, potentially affecting international checkouts and purchase completions.
The root cause of the outage was an API permission issue that was introduced during a routine deployment. Unfortunately, the synthetic tests for the Landed Cost API flow didn’t immediately flag the issue, which caused an extremely uncharacteristic delay to the resolution.
It's important to note that this issue was caused by a very unique set of circumstances. We have just finished an extremely complex and expansive migration project to move all of our merchants to a robust and secure new system. This issue was directly caused by processes related to this now complete migration.
Impact: critical

| **Date** | **Time** |
| --- | --- |
| October 12, 2024 | 22:30 UTC |
| October 13, 2024 | 21:33 UTC |
**How was the issue detected?**
The engineering team noticed a warning of failed quotes in the log files.
**What functionality was affected?**
All landed cost requests during the outage failed for affected merchants.
**What problems did this cause?**
Shoppers of affected merchants were unable to get landed cost quotes, and in many cases complete their checkout.
**What was the resolution of the problem and steps that are being taken for continued follow-up?**
Once the issue was identified, our team acted swiftly to permission issue. After thorough testing, we confirmed the API was fully restored at **21:33 UTC** on Sunday.
**What mitigation solutions will we put in place to prevent this issue from occurring in the future?**
* **Expanded test coverage**: We are enhancing our synthetic tests to include additional token and permission checks, ensuring that potential issues like this are caught earlier.
* **Improved log classifications**: We’re updating our logging processes to better distinguish between warnings and errors, which will enable faster detection and resolution of similar problems in the future.

### **How was the issue detected?**
Synthetic test failures alerted our team.
### **What functionality was affected?**
Increased latency on landed cost quotes, plus a period where landed cost quotes failed.
### **What problems did this cause?**
Landed cost quotes were slow to return and/or failed to return.
### **What was the resolution of the problem and steps that are being taken for continued follow-up?**
The problem was caused by a very large message added to our message queue that could not be consumed due to insufficient resources. The immediate resolution was to increase maximum allocated memory to allow the message queue to clear.
### **What mitigation solutions will we put in place to prevent this issue from occurring in the future?**
To prevent this from happening again, we have decreased the total allowed message size by both the producers and consumers. We are also evaluating techniques to make the message queue more robust to this type of failure.
