Case Study
Caching 30+ Gb/s of Live Cricket — While 130M+ Watched
How Extreme CacheMaster's HTTP caching engine offloaded nearly half of all streaming traffic during the India vs Pakistan T20 World Cup 2026 match — the most-watched cricket event of the year.
The Event
On February 15, 2026, India faced Pakistan in the ICC Men's T20 World Cup at the R. Premadasa Stadium in Colombo, Sri Lanka. It was the most anticipated cricket match of the year — and it didn't disappoint.
India posted 175/7 powered by Ishan Kishan's sensational 77 off 40 balls, then bowled Pakistan out for 114 to win by 61 runs and secure their place in the Super Eights. It was India's 8th win against Pakistan in T20 World Cup history.
The digital audience was staggering. JioHotstar reported over 130 million concurrent viewers as India batted first — shattering the previous record of 59 million set during the 2023 ODI World Cup final. The T20 World Cup 2026 opening day alone clocked 14.7 billion minutes streamed on JioStar.
For every ISP serving cricket fans, this meant one thing: a massive, sustained surge of HTTP video traffic delivered via CDNs like Akamai, all hitting their upstream links at once.

The Challenge
Why live mega-events are the ultimate stress test for ISP infrastructure
Massive Concurrent Demand
Over 130 million concurrent viewers streamed the match online via JioHotstar alone, creating one of the largest live streaming events in history.
Upstream Link Saturation
Without local caching, all CDN traffic must traverse upstream and peering/IX ports, risking congestion and degraded quality for all subscribers.
CDN Traffic Concentration
Live streams delivered by CDNs like Akamai send identical video segments to thousands of subscribers simultaneously — the same content, repeated over every upstream link.
How CacheMaster Solved It
Extreme CacheMaster's HTTP caching engine sits inline on the ISP's network, transparently intercepting and caching HTTP/HTTPS content as it flows through. When a live cricket stream is delivered via a CDN like Akamai, the video is broken into small segments (typically 2–6 seconds each) using protocols like HLS or DASH.
When the first subscriber requests a video segment, it's fetched from the CDN origin and simultaneously stored in the local cache. Every subsequent subscriber watching the same stream receives that segment directly from the CacheMaster cache — at local network speeds, without consuming any additional upstream bandwidth.
During this match, with thousands of subscribers tuned in to the same stream at once, the cache hit rate was exceptionally high. The graph tells the story: the purple cache area nearly matches the blue upstream area, meaning for every 1 Gb/s fetched from the internet, almost another 1 Gb/s was served entirely from local cache.
Without CacheMaster, the ISP would have needed 31.73 Gb/s of upstream capacity to serve its subscribers during peak. Instead, it only needed 18.87 Gb/s — the rest was handled locally.
The Results
Measurable impact from a single live event
Upstream Bandwidth Saved
Nearly half of total peak traffic was served directly from the local HTTP cache, keeping upstream and peering links from being saturated.
Consistent Streaming Quality
Subscribers experienced buffer-free, high-quality streams because cached content was delivered at local network speeds, not bottlenecked by upstream capacity.
Headroom for Growth
By offloading ~48% of peak traffic to cache, the ISP retained upstream capacity for other services and non-cacheable traffic during the event.
No Infrastructure Upgrade Needed
The existing Extreme CacheMaster deployment handled the surge transparently — no emergency upgrades or manual intervention required.
The Bigger Picture
Live sporting events are just one example of traffic patterns that benefit from local caching. Software updates from Microsoft, Apple, and Google; popular video-on-demand content on YouTube, Netflix, and other OTT platforms; gaming downloads; and social media content all follow similar patterns where the same content is requested by many subscribers.
What makes live events uniquely challenging is the simultaneous, concentrated demand. Thousands of subscribers request the same video segments within seconds of each other, creating sharp traffic spikes that can overwhelm upstream links. This is precisely where HTTP caching delivers the highest ROI — one fetch from the CDN origin serves the entire subscriber base.
For ISPs and telcos in regions where cricket, football, or other live sports drive massive viewership, Extreme CacheMaster isn't just a bandwidth optimization tool — it's infrastructure insurance that ensures quality of experience during the moments that matter most to subscribers.
