At approximately 08:00 UTC our engineers began to investigate a large traffic event impacting performance within our Europe and North America regions. 

Standard traffic engineering practices have been deployed in response to this event, in an effort to reduce the potential impact to our customers within the regions. Customer may continue to see elevated errors and latency as mitigation efforts continue to be deployed.

All other products and services are unaffected by this incident.

Our engineers are implementing adjusted mitigation strategies in our North America and Europe regions to continue to balance traffic and manage performance.

Error rates and latency have improved, although customers may still experience intermittent periods of performance impact as traffic engineering continues to be deployed.

Engineering has implemented mitigation strategies and has confirmed a gradual recovery in our North America and Europe regions. 

We are closely monitoring performance in these regions as a top priority as this event continues and will provide a final update once customer and end user experience has been fully restored.

Engineering has confirmed that Europe and North America regions have been fully restored. Customers may have experienced elevated errors and latency from 08:00 to 16:37 UTC.

This incident is resolved.

Affected customers would have experienced impact to varying degrees and to a shorter duration than as set forth above.

Fastly will be adding capacity at our Frankfurt (HHN) data center. End-users may observe connection resets as traffic is migrated onto new hardware, starting on 08 December 2022 at 00:00 UTC.

• Our estimated duration is 300 minutes

In order for customers who use this POP as an Origin Shield to leverage new cache nodes for an expanded cache footprint, customers can either apply a new config version at a time of their choosing, or their shielding configuration will be updated on their behalf 7 days after this maintenance window closes. 

When this change is applied, customers may observe additional origin traffic as new cache nodes retrieve content from origin. Please be sure to check that your origin access lists allow the full range of Fastly IP addresses (https://docs.fastly.com/en/guides/accessing-fastlys-ip-ranges). Customers with any questions or concerns should contact Fastly’s Support team (support@fastly.com).

Fastly is aware of an expected critical vulnerability the OpenSSL project is expected to disclose in the near future. We are studying the currently available information surrounding this vulnerability and do not currently believe that Fastly is vulnerable. We will continue to monitor as additional information is released and will provide our customers with more information as available.

Fastly has reviewed the initial notification from OpenSSL regarding CVE-2022-3786 and CVE-2022-3602. We have analyzed the versions of OpenSSL in use at Fastly, and verified that we do not use OpenSSL 3.x. Fastly and customer usage of Fastly services are not vulnerable to CVE-2022-3786 or CVE-2022-3602.

We're currently investigating potential impact to performance with our CDN services.

Fastly will be expanding Frankfurt into a Metro POP. End-users may observe connection resets as traffic is migrated onto new hardware. As part of this expansion, customers utilizing shielding in the neighboring Frankfurt POP (HHN) will be migrated to the new Metro POP.

Once this maintenance window closes, customers can either apply a new config version at a time of their choosing, or their shielding configuration will be updated on their behalf after 14 days.

When this change is applied, customers may observe additional origin traffic as new cache nodes retrieve content from origin.

Action for Fastly Customers:

1. Please be sure to check that your origin access lists allow the full range of Fastly IP addresses: https://docs.fastly.com/en/guides/accessing-fastlys-ip-ranges. Failure to verify origin access lists will result in origin connection disruption.
2. Customers with any questions or concerns should contact their dedicated technical account team or Fastly’s Support team at (support@fastly.com).
