Overview

What is Hostersi?

Hostersi operates as a high-end cloud architecture and consulting firm rather than a traditional mass-market host.

The company specializes in the design and management of high-availability infrastructures for critical applications and massive traffic events (e.g., e-commerce flash sales). Their expertise spans complex AWS/Azure migrations and hybrid cloud management, acting as an external operations department.

While offering hosting services, their core value lies in 'DevOps as a Service' and architectural consulting. Hostersi is the designated partner for large enterprises and media outlets where infrastructure failure incurs unacceptable operational costs.

Coefficient Applied

This hosting provider's website did not return full HTML content due to bot protection. HTML size was measured as 64KB (under 100KB). Since reliable "Time to 1MB" data could not be obtained, a +109ms coefficient was applied to maintain ranking fairness.

Coefficient Calculation Formula
penalty = (100 - 64) × 2 = +109ms
