Azure is at capacity; GH offers a lot of services for free or heavily discounted. Especially when its public repo. These aren't profit generating for Microsoft, so they are not the priority with the capacity Azure has available. GH is probably struggling with these capacity and budget constraints. They also still have some AWS and non-azure DCs in use.

Once Azure's massive spend is online things will slowly get better.

I think GH/Microsoft got caught by surprise to the huge usage number increase as a result of LLMs. Microsoft started rolling all of its DCs to OpenAI around 2019-2020 to begin LLM training, then we saw a huge GH increase in late 2024 and Azure was just out of capacity for infinite GH scale.

They're actually ramping back up on AWS after Azure failed to scale to their needs.

They planned to be fully off AWS in 2027 but they're continuing to ramp usage.

Azure doesn't scale.

Is there any data on Azure being terrible with stability? Would love to see data than anecdotal stories.
