1) Try increasing number of nodes - > fails with some cryptic message saying number of in use addresses is hitting the quota limit.
2) Search through their absolutely garbage console to go to the exact page which has the quotas. Try editing - > See a tooltip (not even an error message just a tooltip) saying I can't do it my self and has to contact their support.
3) Contact their billing support and ask for quota increase. After taking all the details they redirect me to their sales support.
4) Contact their sales support and its like dealing with second hand car sales people. Even after clearly stating that I'm an existing customer, they want a complete biography of my whole business, its needs and everything else. At the end they say they don't have anyway to actually raise the quote increase request from their side.
5) They have helpfully assigned me a relationship manager for further 'assisting' me with evaluating their products and that I got a meeting request for next week to discuss our 'needs'.
Absolute garbage company with third rate support and sales people. And I can say that with confidence because I had the exact opposite experience with Linode when trying to raise limits on my account. Got a human to both respond and increase the limit almost immediately and I didn't need to provide any details about my business.
I'm with OP - Google products are absolute trash.
