Regarding Cloud VPN SLAs, what is the SLA percentage for Google's standard service?

The SLA percentage for Google's standard Cloud VPN service is set at 99.9%. This means that Google commits to providing at least 99.9% uptime for the Cloud VPN service over a given period, typically defined as a month. This level of availability is often indicative of robust infrastructure and reliability, assuring users that the service will be operational and accessible nearly all the time, accounting for brief outages or maintenance windows.

The commitment of 99.9% translates to an allowable downtime of about 43.2 minutes per month, which is significant but still ensures high availability. This makes the service suitable for many applications that require reliable connectivity without the necessity for absolute zero downtime, which would be indicated by a 100% SLA.

A comparison with other levels of SLAs helps emphasize the robustness of the 99.9% promise. For instance, a 99.5% SLA would allow for more downtime, translating to about 22 hours of potential unavailability per month, which is significantly higher and not conducive for applications that require more stringent uptime guarantees. Similarly, while 99.99% (equivalent to roughly 4.4 minutes of downtime monthly) offers even higher assurance, it is not the standard for Google's Cloud VPN service
