> In January 2021, we completed an assessment of the useful lives of our servers and network equipment and adjusted the estimated useful life of our servers from three years to four years

Does anyone know what the observation was here that made this possible? Have Google's internal workloads not grown in size as quickly as they thought, or is this a "Moore's law is slowing down" thing?

Googler, opinions are my own. I know nothing about this.

I wonder if this was Google's response to the chip shortage? Maybe the cost/benefit (and just sheer inability to get certain parts) made them hold on to hardware for longer.

I don't think the workloads would have much to do with this, probably saw that they were having less failures than anticipated or memory/chip shortages have them keeping equipment around longer than they planned.

My assumption is the hardware was more reliable than expected. If it was about slowing workload growth one might expect them to switch to a usage-based (instead of time-based) depreciation schedule.

Seemingly the latter. Less benefit between generations and more stress resistance in hardware compared to earlier data center practice

That would be an interesting adjustment
