We Identified a problem on our backend when it comes to run Chef to configure instances. Staff on duty is currently working on this matter.

A fix has been implemented and we are monitoring the status of Chef runs across the platform.

The deployed fix addressed the issue, allowing Chef runs to happen smoothly once again. As such we're marking the incident as Resolved. Feel free to open a ticket with Engine Yard Support for any questions, comments, or concerns that may arise.

We're seeing instance failures in one AZ in the N. Virginia AWS region. Customer environments and applications may be impacted by this at the current time. Engine Yard's own cloud.engineyard.com application has been impacted and at this time we are working on restoring service to this application. AWS have yet to official report any issues, but please monitor https://status.aws.amazon.com/ for updates.

Functionality has now been restored to https://cloud.engineyard.com. AWS are seeing connectivity issues in one AZ in the US-East-1 (N. Virginia) region, which is causing instance reachability issues impacting both application functionality and instance control operations. Please open a ticket if you are having issues, and the issue can be monitored via https://status.aws.amazon.com/

AWS have stabilised the impacted AZ and are restoring impacted instances. We are seeing the majority of impacted instances fully functional again. If you see any further issues please contact Support.

AWS has resolved the incident and we are not experiencing issues anymore. Please contact Support for any queries.

AWS are reporting internet connectivity issues in both US-West regions (N. California and N. Oregon), which may be impacting the reachablility of customer's applications and environments hosted in those regions. Amazon are currently investigating and working towards resolution, and the latest updates on the status of the issue can be viewed at https://status.aws.amazon.com/.

We are continuing to work on a fix for this issue.

AWS have now resolved the internet connectivity issues in the two US-West regions and normal service has been resumed.

Amazon are reporting increased API error rates in the US-East-1 (North Virginia) region. Please hold off from making any infrastructure level changes to environments hosted in this region (instance restart, creation and termination) at this time. If you see any issues with your environments or applications please open a ticket.

Amazon have mitigated the issue causing the API errors and therefore the region is functioning as normal again and all Engine Yard infrastructure related operations should now run without issue.

This incident has been resolved.

**Incident Timeline:** * 18:15 UTC: First customer reports issues with Chef _Apply_ runs on instances. * 18:50 UTC: Investigation into the issue links the issue to failures with Portage \(Gentoo package manager\), specifically the failure of customer instances to access the platform’s Portage server. * 20:15 UTC: Further testing has shown the issue to be wide-reaching and impacting all stacks \(stable v1 to v5\) aside from \(the Ubuntu based\) stable-v6. As such an Incident is created to inform customers. * 21:00 UTC: The Portage server is identified and restarted, though remains inaccessible. * 21:30 UTC: Portage server access is gained and direct investigation of connection failures from platform instances is performed. * 21:50 UTC: Flushing of IPTables firewall rules on Portage server restores connectivity of customer instances to Portage. * 22:00 UTC: Re-application of dynamically generated IPTables firewall rules is found to not impact connectivity. * 22:15 UTC: Source of issue is tracked to a change in the format of the AWS IP Range list published shortly before the latest automatic update to the dynamically generated IPTables firewall rules on the Portage server. This change was found to be reverted in later published lists. * 22:30 UTC: Incident is declared as Resolved. **Incident Root Causes:** * Engine Yard instances running stacks stable-v1 to stable-v5 run the Gentoo OS, which utilises Portage as its package manager. Engine Yard curates its own packages through a dedicated Portage server. * Upon a Chef _Apply_ run instances synchronise the local Portage Tree from the Portage server. * For security reasons the Portage servers is fire-walled from the wider internet, but needs to still allow access from AWS IP addresses. * To keep this fire-walling up to date, the Portage server runs a regular task to download the [latest published AWS IP Ranges list](https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html) and utilise this to dynamically generate firewall rules, granting these ranges access. * In the \(UTC\) evening of 1st April Amazon published a new IP list, which contained an additional field, not previously included in the list. * This additional field led to a failure of the list to be parsed by the firewall rule generation script, leading to the Portage server no longer granting access to the AWS IP ranges, thus blocking access to Portage from customer instances. **Incident Impact:** Customers on stacks stable-v1 to stable-v5 saw Chef _Apply_ run failures on creation of new instances or configuration of existing instances when such runs required updating of the Portage Tree or installation of packages. This failure applied to all regions. The incident did impact the deployment or running of customer applications. **Incident Corrective Actions:** We have reached out to Amazon regarding the changes to the published IP Range list, with regards to why the list was published in such a state and if such changes will be published again in future. Engine Yard will be undertaking a review of the dynamic fire-walling script, in order to prevent future parsing failures resulting in unwanted firewall lockdowns. We shall also be reviewing and improving internal documentation and knowledge sharing in order to improve investigation and resolution of any future Platform issues.

The Engine Yard Cloud Dashboard (https://cloud.engineyard.com/) is currently offline due to AWS issues in a particularly availability zone causing connectivity issues for a failing component. Actions are being undertaken to restore service at this time. Customer's may also see issues of their own due to the connectivity issues which are affecting some instances in a single AZ of the US-EAST-1 region. If you see any issues please submit a support ticket via (https://support.cloud.engineyard.com) or should you be unable to login to your Engine Yard account please contact us in IRC (irc.freenode.net, channel #engineyard).

The failing component of EY Cloud has now been replaced in order to restore connectivity and service, bringing the Cloud Dashboard back online. Any operations that were being attempted at the time of the failure should be checked and repeated as necessary. AWS continue to face issues in the single US-East-1 AZ with instances being impaired and EBS volumes experiencing degraded performance, so some customers may still be impacted. Should you see any issues or require further assistance please submit a support ticket.

Engine Yard hasn't seen any further occurrence of the problem. AWS has marked as resolved the issues affecting a single AZ on US-East-1. As such, we're marking the issue as 'Resolved'.

**Incident Timeline:** * 13:20 UTC: Our Virtual NOC alerts us to the failure of the monitoring URLs for the Engine Yard Cloud Dashboard. At this point EY Cloud is returning errors and so is inaccessible for customers. * 13:30 UTC: Investigation of the issue identifies the source as being a failed AWS instance, this instance is restarted at AWS in order to restore the instance. The restart hangs in the “stopping” state at AWS. * 13:35 UTC: Amazon publish a Service Status message to inform customers that a connectivity issue is affecting some instances in a single Availability Zone in the US-East-1 Region. * 13:35 - 14:45 UTC: Further attempts to restore the failed instance are unsuccessful due to the AWS issues, as are attempts to snapshot or reassign the instance’s EBS volume. * 14:45 UTC: Another platform instance running in the Cloud Dashboard environment is repurposed in order to take the place of the failed instance. * 15:00 UTC: Reconfiguration of the Cloud Dashboard application completes successfully and service is restored. * 15:00 UTC and onwards: With the Cloud Dashboard restored Engine Yard Support engineers work with customers to replace affected instances with alternative instances in unaffected AWS AZs. * 20:35 UTC: Amazon announce the issue is resolved and service is restored. Certain EC2 instances, RDS instances and EBS volumes remain in a failed state and cannot be restored by Amazon automatically, so EY Support continue to work with customers to restore these. **Incident Root Causes:** * **From AWS**: At 4:33 AM PDT one of ten data centers in one of the six Availability Zones in the US-EAST-1 Region saw a failure of utility power. Our backup generators came online immediately but began failing at around 6:00 AM PDT. This impacted 7.5% of EC2 instances and EBS volumes in the Availability Zone. Power was fully restored to the impacted data center at 7:45 AM PDT. By 10:45 AM PDT, all but 1% of instances had been recovered, and by 12:30 PM PDT only 0.5% of instances remained impaired. Since the beginning of the impact, we have been working to recover the remaining instances and volumes. A small number of remaining instances and volumes are hosted on hardware which was adversely affected by the loss of power. We continue to work to recover all affected instances and volumes and will be communicating to the remaining impacted customers via the Personal Health Dashboard. For immediate recovery, we recommend replacing any remaining affected instances or volumes if possible. * **From Engine Yard:** The root cause of the issue was quickly identified to be the failure of an AWS instance, responsible for the running of a core component of the EY Cloud Platform . The inability for any other platform instances to communicate with this instance resulted in errors in the platform. It was initially desired to restore the existing instance, or failing that, utilise the snapshot to retain data, but the AWS issues prevented such actions, leaving the only option to be to repurpose another existing instance. Once this action was completed, service was restored. **Incident Impact:** For the period that the Engine Yard Cloud Dashboard was offline no customers were able to view or manage their environments through either the Dashboard or the API, so were unable to make environment or application changes. Running instances outside of the subset of failed instances in the single AZ of US-East-1 were unaffected, so the majority of customer applications were not impacted. For those with instances in the affected AZ, application impact was dependent on the role of the impacted instances, with database and application master instances resulting in application downtime, whilst slaves instances most likely not. EY Support staff worked with customers to restore failed instances where practically possible within the limitations of the AWS issues. **Incident Corrective Actions:** Engine Yard will be working to strengthen the platform environments in order to ensure the highest resilience across all components in order to minimise the disruption from any future infrastructure failures.

On August 15, 2019 at 20:45:43 GMT, our monitoring system alerted that a core component of the platform was not responding. This component is responsible of providing information on stack versions and access to Chef recipes used to configure instances. At 20:55:49 GMT our Support Team begun investigating the issue. At 21:00:01 GMT it was identified that the application running this component couldn't connect to the database. At 21:01:47 GMT it was detected that the db instance had restarted itself and was entering recovery mode. At 21:02:48 GMT the component resumed services. At 21:14:42 GMT, after both automatic and manual testing reported no failures, the issue was deemed as solved.
