Traffic Served measures the bytes the CDN sent to clients in a given window. It drives your bandwidth bill and signals whether traffic patterns are shifting under you.

Traffic Served Statistics

What it tells you

  • Total bytes delivered to end users.
  • Period-over-period change (today vs yesterday, week vs week).
  • Trend lines that surface launches, viral spikes, and outages.

How to read the chart

Pull via API

Response (truncated):
See the CDN API reference for filters (granularity, per-PoP breakdown).

Common patterns

Cost levers

  • Raise cache hit ratio. Higher HIT% = same user-facing bytes, less origin egress.
  • Compress text. Enable Gzip / Brotli in cache rules.
  • Right-size images. Use Image Optimizer with format=auto and capped widths.
  • Cap query-string variants. A noisy cache key duplicates the same bytes.

Operational tips

  • Daily totals to finance. Pipe API totals into your billing spreadsheet or BI tool.
  • Per-path breakdowns. Use the path filter to find the top 10 bandwidth consumers; cache or compress them harder.
  • Alert on rate, not total. A 5× hourly spike is more actionable than absolute totals.
