Comcast's waiving of data caps has had little effect on internet speeds even as peak traffic increased 32%, giving lie to their stance that caps are needed
Pandemic shows Comcast could kill data caps forever without ruining its network. — Back in the before times …
Context & Ripple Effects
Comcast's data-cap defense has been eroding for years: a leaked internal memo reportedly admitted caps aren't about network performance, and by 2018 the company had quietly disabled its congestion-management throttling system while still charging overage fees in 27 states. The cap itself has only moved when convenient — a raise from 300GB to 1TB that came bundled with a $50/month unlimited option.
The pandemic waiver turned into an unplanned natural experiment. With peak US traffic up 32% over pre-pandemic levels and video streaming up 70% versus 2019, Comcast's network absorbed the load without caps in place — and speeds held, which is precisely the failure mode its cap rationale predicted.
First-order effects
- Comcast's stated justification for caps — protecting network performance under heavy load — is directly contradicted by its own traffic numbers during the waiver period, leaving overage fees in 27 states exposed as pure revenue rather than engineering necessity.
Second-order effects
- The Stream TV precedent shows how Comcast already treats cap accounting as a competitive lever — exempting its own IP cable service because it rides the cable network rather than 'the Internet' — so any permanent cap regime invites scrutiny of which traffic counts and whose.
- Rival ISPs face pressure to match cap waivers or defend their own caps against the same evidence, since one large operator demonstrably ran uncapped at record peak load without degradation.
Third-order effects
- If regulators or courts treat this episode as evidence that residential capacity is not scarce at the margin, usage-based pricing for home broadband shifts from a network-management tool to a contested billing practice — with the leaked memo and the throttling shutdown as the documentary record.
The trend: Broadband data caps are being exposed as a revenue instrument rather than a congestion tool, as operators' own traffic disclosures undercut the scarcity argument they were built on.
