In 2025, many companies learned a practical lesson about infrastructure reliability.
Not from whitepapers or architectural diagrams, but from real outages that directly affected daily operations.
What stood out was not that failures happened — outages have always existed — but how broadly and deeply their impact was felt, even by teams that believed their setups were “safe enough.”

When a single region becomes a business problem
One of the most discussed incidents in 2025 was a prolonged regional outage at Amazon Web Services.
For some teams, this meant temporary inconvenience. For others, it meant hours of unavailable internal systems: CRMs, billing tools, internal dashboards, and operational services.
What surprised many companies was that they did not necessarily host workloads directly in the affected region. Dependencies told a different story. Third-party APIs, SaaS tools, and background services built on the same infrastructure became unavailable, creating a chain reaction.
For an online business, even a few hours of full unavailability can mean a meaningful share of daily revenue lost. But the bigger cost often appeared later: delayed processes, manual recovery work, and pressure on support teams.

When servers are fine but the network isn’t
Later in the year, a large-scale incident at Cloudflare highlighted a different weak point.
Servers were running. Data was intact. But network access degraded.
From a user perspective, the difference did not matter. Pages failed to load, APIs returned errors, and customer-facing services became unreliable. Even teams with redundant server setups found themselves affected because the bottleneck was outside their compute layer.
This incident changed how many engineers and managers talked about reliability. “The servers are up” stopped being a reassuring statement if the network path to those servers could fail in unexpected ways.

The quiet accumulation of “minor” failures
Not every problem in 2025 made headlines. In fact, most did not.
Many teams experienced:
• intermittent routing degradation,
• partial regional unavailability,
• short network interruptions that did not trigger incident alerts.
Individually, these issues were easy to dismiss. Collectively, they created friction. Engineers spent more time troubleshooting. Deployments slowed down. Systems became harder to reason about.
Over time, these “minor” failures affected velocity just as much as a single large outage.

What changed in how businesses evaluate infrastructure
By the end of 2025, the conversation inside many companies had shifted.
Instead of asking “Which provider is the biggest?”, teams started asking:
• How quickly can we recover if a region fails?
• What dependencies exist outside our direct control?
• Can traffic or workloads be moved without a full outage?
• How predictable is the infrastructure under stress?
This shift mattered. Reliability stopped being a checkbox and became an architectural property that had to be designed, not assumed.

Why some teams reconsidered VPS-based setups
An interesting side effect of this shift was renewed interest in VPS infrastructure — not as a “cheap alternative,” but as a way to regain architectural control.
For certain workloads, VPS deployments allowed teams to:
• spread services across multiple regions,
• reduce reliance on a single platform ecosystem,
• make network behavior more explicit and testable.
Some teams began combining hyperscalers with VPS providers, treating infrastructure diversity as a form of risk management rather than technical debt. Providers commonly discussed in this context included Hetzner, Vultr, Linode, and justhost.ru, each used for different regional or operational needs.

A practical takeaway from 2025
The main lesson from 2025 was not that clouds are unreliable.
It was that reliability cannot be outsourced entirely.
Infrastructure failures became a management issue as much as a technical one. Teams that treated outages as architectural scenarios — and planned for them explicitly — recovered faster and with fewer side effects.
By contrast, teams that relied on reputation or scale alone often discovered their risk surface only after something broke.

Final thought
Infrastructure in 2025 stopped being background noise.
It became a variable that businesses actively model, question, and design around.
Not because outages suddenly appeared, but because their real cost became impossible to ignore.
