18 Loaderio incidents · 2013년 12월 — official updates, affected components, duration and resolution details.
We're investigating database performance issues that are causing intermittent errors and long page load times on the loader.io web interface, and delays in processing the load test queue.
Test queues have caught up, and web interface and API appear to be functioning as expected now.
Database performance and test queue processing is back to normal
On Jan 2, 2023 the loader.io website, API, and test running services became unavailable due to an expired TLS certificate in a backend service that manages service credentials. The certificate had been renewed, but was not distributed to all servers that needed it. When the certificate expired, Loader's orchestration system was unable to read credentials for internal connections to databases and other services, and several services failed as a result, including the web interface and the test running & scheduling jobs. Our team was not notified due to a separate failure of alerting systems, and the team was not in the office because of the observance of the New Years Day holiday on the Monday after new years day. As soon as a team member noticed the outage, service was restored by distributing the renewed certificate to the credential service, and restarting the other failed services. - Test settings, results, and other account information in the loader.io web interface was inaccessible - Tests that had been scheduled for Jan 2, 2023 were not run during their scheduled time, and instead would have run after service was restored, early on Jan 3 2023 - Some scheduled tests may have been scheduled twice in error when service was restored, due to retries and delays processing the backlog of tests We are reviewing our automation and monitoring systems to ensure that critical systems are better automated, and that our team receives alerts promptly!
We are investigating an issue connecting to Loader's primary database
A replica has been promoted after Loader's primary database failed. Systems are functional and we continue to monitor closely
This incident has been resolved.
We are investigating a problem with our website load balancers.
Systems are getting back to normal; we continue to monitor closely
This incident has been resolved.
A recent configuration change caused some of our web servers to stop responding. You may have seen HTTP 502 "Bad Gateway" errors from our web interface and API. The problem has been fixed and we will continue to monitor closely.
All web traffic is stable, so we are marking this resolved.
We are looking into an issue where some tests are not running
The cause of test delays has been identified and fixed. We are continuing to monitor as the test queues catch up.
This incident has been resolved.
Some tests are being queued for longer than usual, we are investigating the cause of the slow-down
Tests should be running normally now
One of our load generation machines stopped responding this morning and has caused a few tests scheduled on it not to run. It has been removed from our fleet of load generators and affected tests should start running. We will be monitoring closely to make sure the issue is resolved.
Tests are running normally now
We are currently investigating this issue.
Delayed tests are starting to run, and new tests should run as expected. All systems operational :)
Tests are now running normally.
Some tests against https endpoints are not sending the correct number of requests. We are currently working to resolve this issue.
We rolled back a recent deploy, https tests should be behaving normally again.
We are investigating an issue where test results do not update as the test runs. Tests are running and results do appear on page refresh.
test results are now coming through and updating live as the test runs
We are currently experiencing an unexpected service outage. We are working on resolving the issue.
We've restored service.
We are investigating a networking issue that is preventing some tests from running correctly.
One one our nodes inside of EC2, DNS was resolving EC2 hostnames to public IP addresses instead of internal ones, which prevented some of our internal systems from communicating properly. DNS is resolving properly again.
The server reboot is going to take longer than anticipated. We should be back around 8:15 AM EDT.
We're back up, but our queues are a little backed up, so tests may take a little longer to start for a bit.
This incident has been resolved.
We are investigating an issue with our load generators causing a few tests to lose some results
load generation is performing normally, but we will keep monitoring to make sure the issue is resolved
This incident has been resolved.
Our web and API are down right now because of a deploy gone wrong. We're working on getting operational again as soon as possible.
And we're back. Tests should be verifying and running as usual now.
Investigating some stalled tests from the past hour
Some network issues around 10:20AM EST caused a few tests to stall. Those tests have been aborted and systems operational now.
A small number of users may have experienced the "preparing screen of death" intermittently over the last 12 hours, where a test shows a preparing message and even the "abort test" button couldn't get you out of it. This was caused by EC2 capacity issues at Amazon, combined with a bug in our handling of that error. A fix for the bug in our code has been deployed, and if you had a test stuck at the preparing screen, we have aborted it for you - instead of the preparing screen, you should now see a message indicating that your test has been aborted. You can run the test again from there.
