Missing EC2 g6e instances in Ireland (eu-west-1)

Unfortunately, AWS does not publicly share roadmaps or timelines for when specific instance types will become available in particular regions. This includes G6e instances in eu-west-1 (Ireland). While I can confirm that G6e instances are indeed available in eu-central-1 (Frankfurt) and eu-north-1 (Stockholm) as you mentioned, there is no publicly available information about when or if they will launch in Ireland.

For the most accurate and up-to-date information about instance availability in specific regions, I recommend reaching out through the AWS Support Center at https://console.aws.amazon.com/support/. If you have an AWS Support plan that includes access to technical account management, that would be your best avenue for discussing your specific requirements and potentially getting insights into regional availability that might help with your planning.

In the meantime, you might consider whether deploying in eu-central-1 or eu-north-1 could work for your use case, keeping in mind factors like latency requirements, data residency considerations, and any regulatory constraints specific to your workload.
