May 2025 – In an era where cyber threats loom larger than ever, one cloud hosting provider just proved it can take a punch — and stay standing.
Last Thursday, CloudBlast.io, a rising player in the cloud VPS hosting space, successfully mitigated a massive 472 Gbps Layer 4 DDoS (Distributed Denial of Service) attack. The scale of the attack raised eyebrows across the industry, not only for its raw volume but for its suddenness and precision. According to the company’s incident report, the onslaught was detected and neutralized within seconds — thanks to a combination of edge-based filtering, 2.5 Tbps DDoS protection, and their robust in-house mitigation stack.
"It wasn’t our first rodeo," said Markus Weber, the lead infrastructure engineer at CloudBlast. “But the scale was unprecedented. We've dealt with 100, even 200 Gbps floods — this was more than double. Yet our systems held.”
CloudBlast.io, known for its low-latency virtual machines and hourly billing flexibility, operates out of multiple high-performance datacenters using AMD EPYC hardware and ultra-fast NVMe SSDs. Their 10 Gbps standard connectivity per VM already puts them ahead of many competitors — but this attack was a real-world stress test no simulation could mimic.
The assault lasted a little over 8 minutes and primarily targeted Layer 4 — the transport layer — attempting to overwhelm TCP/UDP ports across multiple nodes. But thanks to their DDoS filtering appliances and intelligent traffic scrubbing methods, end users reportedly experienced no noticeable downtime.
"We didn’t just withstand the storm," Weber added. "We learned from it. The data we gathered will help refine our threat models even further."
What’s perhaps most impressive is that CloudBlast managed this level of defense without the backing of a major hyperscaler. Many small- to mid-sized hosting providers would have crumpled under the pressure or seen extensive downtime. CloudBlast, however, has consistently emphasized owning its hardware and colocating strategically — giving it an edge in control and response speed.
Industry analysts have started to take notice.
“This incident is a litmus test,” said Paula Klinger, a cybersecurity consultant with over a decade of experience. “A lot of providers talk big about DDoS protection, but when traffic starts pouring in at 470+ Gbps, you either have the chops — or you don’t. CloudBlast clearly does.”
With the attack now behind them, the company has taken a measured approach in sharing details. No specific clients were named, and logs have been anonymized, though CloudBlast hinted that the target was a high-traffic gaming client, which aligns with the type of Layer 4 floods often seen in that sector.
At a time when trust in cloud providers is closely tied to resilience and transparency, CloudBlast.io may have just earned itself a serious credibility boost.
