Last week, Signal, a messaging app that puts privacy first, went offline briefly. The cause was an outage at Amazon Web Services (AWS), which hosts Signal’s servers. Many users and critics questioned why Signal depends so heavily on a single cloud provider. CEO Meredith Whittaker explained that there aren’t many options available right now.

Whittaker pointed out that the infrastructure market is dominated by just a few big players. She said, “The problem is the concentration of power in the infrastructure space, which means there is effectively no real alternative: the entire stack is effectively owned by 3-4 players.” This means companies like Signal don’t have many choices when it comes to where they host their services.

She added that the focus shouldn’t just be on why Signal uses AWS but on understanding the larger landscape. The infrastructure needed for a global, real-time messaging platform is complex and costly. As a result, most companies end up relying on the same handful of cloud giants, which creates a kind of digital monopoly.

This reliance on a few big cloud providers raises concerns about resilience and control. When there’s an outage at one of these providers, many services can go down at once. That’s what happened to Signal last week. While the outage was temporary, it highlighted how vulnerable these services can be when they’re so dependent on a small group of companies.

Some critics argue that this concentration of power threatens the openness and resilience of the internet. If only a few companies control the infrastructure, it can limit competition and innovation. It can also make it harder for smaller or newer services to compete, since they don’t have the resources to build their own infrastructure.

Whittaker emphasized that the industry needs to consider alternative ways to build and distribute digital infrastructure. She suggests that more options could lead to a more resilient and fair digital environment. However, creating these alternatives would require significant investment and cooperation across the tech industry.

In the meantime, Signal and other services will likely continue to depend on major cloud providers for the foreseeable future. The challenge is balancing the benefits of cloud computing—like scalability and cost efficiency—with the risks of over-reliance on a few giants. As users and advocates push for more diversity in infrastructure, the industry may see new solutions emerge over time.

This situation underscores a broader issue about how digital services are built and maintained. The choices made today could shape the future of online privacy, resilience, and competition. As technology evolves, finding a way to diversify infrastructure might become a key goal for a healthier internet.
