For an existing Dedicated Interconnect connection, you can modify its
description, technical contact email address, and the number of circuits
(the capacity).
If you modify the description or email address, these changes are immediate.
If you change the number of circuits, the existing Dedicated Interconnect connection and
its VLAN attachments continue to operate as normal because the circuit bundle
uses Link Aggregation Control Protocol (LACP). Traffic isn't disrupted.
If you increase the number of circuits, you follow a process similar to
creating a connection.
Google sends you an LOA-CFA with your requested changes. You send this
document to your vendor to grant them authorization to complete the work. New
circuits aren't usable until they are provisioned and
tested.
If you decrease the number of circuits, Google removes the requested number of
ports from the bundle and notifies you which circuits to remove. You then
need to contact your vendor to remove those Dedicated Interconnect connections.
The following items can't be modified for existing Dedicated Interconnect connections:
The link type on a Dedicated Interconnect connection. For example, changing the
circuit from 10 Gpbs to 100 Gbps. If you want to migrate to
100 Gbps, you must first provision a new 100โGbps Dedicated Interconnect
connection alongside your existing 10โGbps connection, and then
migrate the traffic onto the 100โGbps connection.
For the Dedicated Interconnect connection that you want to modify, select it.
On the connection's detail page, click Edit.
Modify your Dedicated Interconnect connection:
Description: Information about the connection.
Capacity: The total capacity of your connection, which is
determined by the number and size of the circuits that you order.
Select one of the following options:
1 x 10โGbps circuit in 10โGbps increments up to 8 x
10โGbps (80 Gbps) circuits
1 x 100โGbps (100 Gbps) circuit
2 x 100โGbps (200 Gbps) circuits
Technical contact: An email address where notifications
about this connection are sent. You don't need to enter your own
address; you are included in all notifications. You can
specify only one address.
Click Save.
To confirm your changes, click Done.

Modify an existing Dedicated Interconnect connection by running the following command:
Replace UPDATED_COUNT with the total number of circuits
of type link-type.
For example, if you have a 20โGbps Dedicated Interconnect connection and want
to make it 40 Gbps, use --requested-link-count=4.
Billing for new circuits starts after they're ready to use (all
tests
have passed) or 30 days after your order is received. You aren't charged
before then. You can cancel your order by reverting to the original number of
circuits. Billing for removed circuits stops when the LACP bundle is resized.
