ReservedInstancesLimitExceeded error for a new account of existing organization

Hi Mark,

I created the new account few day back. I already have one on-demand g4dn.2xlarge instance running for the last 5-6 days on the account.

Do I still need to run two t2.small instances for 20 minutes?

Hi Mark,

I launched two t2.small instances and waited for a couple of hours.

I am still getting the same error when I try to purchase the reserved instance

Hi Mark

I've also run into this issue -

• We've been running 3 different instances for over 400 hours each + RDS instances + Elasticache instances
• Had a payment of $400+ taken for the first month
• The same reported reserved instances limit (20)

And we're still unable to purchase reserved instances. We have a support ticket open to resolve the issue however I think two things are required by AWS

• Clear documentation if it is not expected new accounts should be able to purchase RIs (or directions to this)
• A process to ensure they can

In our case the cost calculator was used to provide a cost estimate to a client and if we're unable to apply reserved instances then we are over budget due to what appears to be an arbitrary limit imposed. We maintain a range of AWS accounts for other clients and have not encountered this issue.
