A game launch represents months of development and significant marketing spend. On launch day, player interest peaks, but so does the risk that something will go wrong.
Diablo 3’s Error 37 became a meme. Cyberpunk 2077’s launch left over a million players stuck mid-download. Bandwidth for Call of Duty: Warzone’s launch was so severely throttled that players couldn’t download the game. In each case, players were ready, but the delivery infrastructure wasn’t.
Your CDN is the touchpoint where your business and your players connect. Every download, patch, and content asset passes through it. While CDNs are built to handle global scale, launch days put extreme pressure on your network. Massive failures are rare, but regional and performance issues are far more common. If your teams don’t have visibility into these issues, they’ll surface through player complaints, refunds, and churn.
Game publishers typically use multiple CDN providers to build resilient networks. But resiliency and visibility are different problems. A resilient network reduces the frequency of failures. Visibility is what lets your team find and fix the ones that happen anyway, before players churn. Most publishers have some visibility, but not enough.
This post will cover:
- How CDN performance is connected to revenue.
- The maturity cycle for businesses, from CDN dashboards to unified CDN visibility.
- The business value of complete CDN visibility.
CDN Performance Is a Revenue Problem, Not Just an Infrastructure Problem
The business cost of CDN underperformance can be difficult to measure. A player who can’t download a game at launch either waits to download later, asks for a refund, or moves on. Only the refund generates a record that your finance team can see. The player who waited but churned a week later, frustrated by a degraded experience during a window that should have been peak engagement, is harder to attribute. The player who never downloaded or complained is completely invisible. Support ticket volume and refund rates are lagging indicators that only come after the damage is done.
Launch windows concentrate this exposure. Day-one players are most likely to generate word-of-mouth publicity, reviews, and social proof. A degraded experience during that window doesn’t just affect the players who experienced it. It also affects the players who read their reviews, watched their streams, and decided whether or not to buy the game. That downstream effect doesn’t appear in any CDN performance report.
For publishers that have limited CDN visibility, the challenges are even greater during launch windows. Regional delivery problems might not show up in aggregates or sampled logs. Later, when you discover that your latest game didn’t sell well in a specific region, you won’t have the data to understand that the problem was a delivery issue, not advertising misalignment or product fit.
You need complete visibility into your CDN networks so you can solve infrastructure problems when they arise, before they become revenue problems. Protecting the touchpoint between your games and players is crucial for your brand and bottom line.
The Journey to Complete CDN Visibility
Most game publishers don’t arrive at full CDN visibility in a single step. They move through a recognizable progression towards maturity, each stage representing a genuine improvement over the previous stage. The reward of maturity goes beyond faster detection and mitigation, and more resilient infrastructure. It’s also the ability to connect infrastructure decisions to revenue, better plan for capacity, and use the full request history of CDN logs to make business decisions based on how players interact with your content.
Built-In CDN Dashboards
CDN providers have pre-built dashboards. They do exactly what they’re designed to do—provide a snapshot into the health of the CDN. For smaller launches that use a single CDN, a CDN dashboard may provide enough visibility. However, this approach causes problems for bigger launches and multi-CDN infrastructure.
- Fragmentation: Each provider reports its own metrics in its own format, on its own timeline. A game publisher using three CDN providers must manage three dashboards, all with different metrics. There’s no way to correlate or compare data across providers, making it impossible to understand how your delivery network is functioning as a whole. Correlation must happen manually, a time-consuming process.
- Aggregation: CDN dashboards typically aggregate, which smooths over regional behavior where the most common problems arise. Teams have less visibility into how specific points of presence (PoPs) and ASNs (covering specific IP addresses) are behaving, and typically they won’t have access to full-fidelity raw logs for root cause analysis and forensic investigation.
As publishers mature and develop resilient, multi-CDN architectures, they move into the next step of the journey.
General Purpose Observability Platforms
Platforms like Datadog and Splunk unify telemetry from application infrastructure, cloud services, and network layers into a single view. They come with mature dashboards, advanced query capabilities, and the ability to drill down into raw logs. The fragmentation problem that makes multi-CDN monitoring painful is exactly the kind of problem they’re designed to address.
However, launch days create massive spikes in traffic, which quickly turns into terabytes of log data. For example, gaming platforms using Hydrolix can ingest more than 20 million rows of log data per second, and traditional observability platforms aren’t designed for this scale.
To manage the scale and cost of massive events, general-purpose observability platforms rely on sampling, ingesting a fraction of log events and inferring behavior from the subset. However, request volume spikes by orders of magnitude precisely when delivery problems are most consequential, and a regional error pattern affecting a small percentage of download attempts in a specific geography may never appear in sampled data at all.
Observability platforms can solve many problems well, but at scale, your teams will run into significant issues with cost, retention, and performance unless they compromise on data fidelity and visibility.
At this stage in the journey, major game publishers are typically dealing with complex, multi-CDN architectures, limited network visibility, and high costs. Sampling makes it challenging or even impossible to get to the root cause of many issues, while short retention windows leave teams without the context they need to complete post-mortems and learn from past events.
Observability platforms are also walled gardens—designed to pull in data from many sources, but not to use that data across the business for other use cases such as business intelligence.
Unified CDN Visibility
The final stage in the maturity journey is complete, unified visibility across your entire CDN infrastructure. It consists a platform with these ingredients:
- Full-fidelity log retention: You should be able to capture every request, every error, and every region without sampling or aggregation. If a regional error pattern affects 2% of download attempts in a specific geography, it needs to appear in the data, or it may never surface at all.
- Standardized data across providers: Logs from every CDN should feed into a single table in a common schema. This makes cross-provider comparisons and unified queries routine, not manual correlation exercises.
- Granular segmentation: To quickly surface issues, you need visibility into ASNs, points of presence (PoPs), and regions, not just aggregate delivery performance.
- Real-time query performance at scale: Launch traffic volumes stress both ingestion and query layers simultaneously. The system has to return answers at the moment they’re needed, not twenty minutes later.
- Long-term retention: A complete operational record of every launch provides value for capacity planning, provider evaluation, and routing decisions, so you can continue to make each launch day better than the last. When a title underperforms in a specific region, you have the delivery data to confirm or rule out infrastructure as a cause, so you can improve on each launch.
- Proven at major events: CDN observability at launch scale isn’t a theoretical problem. Platforms that have operated through events like Super Bowl broadcasts have demonstrated that the architecture holds under the kind of concentrated, unpredictable demand that game launches produce.
Unified CDN visibility allows you to shift from a reactive stance to proactive monitoring. Your teams can find and fix issues faster, making launch day more successful and preventing revenue loss. It also provides the tools your business needs to connect infrastructure decisions to revenue and make your CDN architecture more resilient for future launch days.
From Infrastructure Decisions to Revenue Outcomes
A game publisher at the final stage of the maturity journey has a complete, queryable record of how every player interacted with every piece of content and download across every CDN, without gaps introduced by sampling or aggregation.
When a title underperforms in a specific market, you can determine whether delivery infrastructure was a contributing factor, not because someone filed a support ticket, but because you have the raw data to answer that question. When a provider shows a pattern of elevated error rates in a specific region across multiple launches, you have the evidence to act on it in contract negotiations with your CDNs or future routing decisions. When you plan capacity for the next major release, you’re working from a complete picture of prior releases, including the spikes that sampled data would’ve missed.
Teams at this stage don’t just respond to problems faster. They have a deep understanding of how delivery infrastructure behaves under pressure and how it’s directly tied to revenue.
