Sorry, users are consuming and blocking floating IPs quicker than we can recover them since they are not freed up automatically.
This will remain an issue and cannot be resolved by providing more floating-IPs.
We will try to release some unused addresses.
Please note that

• a VM must be attached to a private (tenant) network which is connected to a router (you need to create that router and network/subnet in your tenant).
• The router's default gateway than can be set to either the "ext-net-public" or the "ext-net-federation" networks. After doing that you can associate a floating IP.from a public network.
• Two firewalls are between public Internet and your VM then: one you can control by setting a security rule for your VM instance, the other one must be configured by the node. Please inform us about the ports you need to be open.

Please apologise the late response – there has been an potential issue with the help-desk during this period mailer so you might not have received the response to your request.
