Is Aptible down?

AWS is experiencing an issue with their APIs in us-east-1, and many services are impacted at this time. This may lead to failed operations. To avoid further issues, we have disabled operations in this region while we understand the full impact.

Operations remain disabled in us-east-1 while we continue to investigate AWS networking issues in the region. We are testing mitigations and will restore operations as soon as it is safe to do so. We will provide another update no later than 10:00 AM Eastern Time.

We have applied a mitigation and re-enabled operations in us-east-1. We are monitoring for stability and will resolve this incident once we confirm conditions remain stable.

This incident has been resolved.

We are aware of delayed and timed-out requests to the LLM Gateway. We have made some changes to help minimize the impact while engineers continue to address the root cause.

We have increased resource capacity, and we are monitoring the results.

After a regression in performance starting at 9:57 UTC (5:57 EDT) and lasting until 11:12 UTC (7:12 EDT), we've deployed a potential fix and updated our service scaling. We are continuing to monitor whether these changes fully resolve the issue before closing this incident.

Following the fixes deployed per the previous update, we have seen stable performance on the LLM Gateway since 7:12 EDT and are resolving the issue. The root cause of this issue was a severe performance degradation in 3 specific endpoints: • `GET /models` • `GET /v1/models` • `GET /metadata/models` ...all of which return a list of available models. The performance issue on these endpoints was severe enough to cause significant request queueing and degraded performance for other unaffected endpoints. The fix we deployed added caching on this endpoint to ensure fast responses. Since those fixes have been deployed, we are no longer seeing request queueing or impacts to other LLM Gateway API endpoints.

As part of our security policy and ongoing commitment to protecting customer workloads, we are applying patches for a newly disclosed Systemd vulnerability (CVE-2026-40226) across our platform. This patching will be rolled out automatically over the next several days. During this process, you may experience a momentary network disruption to running applications and databases. Customers configured for high-availability with horizontally-scaled services should experience little to no disruption from this update. No action is required on your part. If you have any questions or concerns, please reach out to our Support team at https://contact.aptible.com/.

There is some partial service degradation with log drains configured to send to Mezmo where not all log messages are being sent. Mezmo is rejecting logs over a certain size. We are actively investigating this issue with the upstream provider.

As of 18:42 UTC the upstream provider began to accept log messages again consistently and this issue is now remediated.

Aptible is aware of “Dirty Frag,” a recently disclosed Linux kernel vulnerability that may allow local privilege escalation under certain conditions [0]. We have taken action across the Aptible platform to protect all customer workloads against this vulnerability. No customer action is required at this time. We will continue to monitor upstream kernel, distribution, and security vendor guidance related to this vulnerability and will take any additional action if needed.
