Google Cloud Is Doubling Peering Egress Costs on May 1 — Here's What to Audit Before Then

On May 1, 2026 — eleven days from now — Google Cloud is doubling CDN Interconnect and Direct Peering rates in North America, from $0.04/GiB to $0.08/GiB¹. If your architecture routes egress through Cloudflare, Akamai, or Fastly, you are almost certainly billed at CDN Interconnect rates already, whether you know it or not². Here is how to measure your exposure and rank your options before the invoice changes.

What’s Actually Changing on May 1

Three billing products are affected: CDN Interconnect, Direct Peering, and Carrier Peering¹. The price increases vary by region:

Region	Current rate	New rate	Increase
North America	$0.04/GiB	$0.08/GiB	+100%
Europe	$0.05/GiB	$0.08/GiB	+60%
Asia	$0.06/GiB	$0.085/GiB	+42%

Note that Google bills in GiB (gibibytes, base-2), not GB (gigabytes, base-10). That 7% gap matters at scale — most cost calculators default to GB, so your estimates will undercount slightly¹.

Six billing SKUs carry these changes: 984A-1F27-2D1F, F603-6008-38E5, 9428-46F3-3796, B1FE-19F7-6D1B, 900C-8E7C-91F5, 30DD-9D90-52CE¹. Regular Cloud CDN egress from origin — the non-peering path — is not affected by this announcement.

Who Is Silently Affected

This is the most likely source of surprise invoices post-May 1. Teams that chose a third-party CDN for performance or cost reasons may have been accumulating CDN Interconnect billing without realizing it. The doubling in North America is a direct hit to that architecture.

How to Audit Your Exposure in 10 Minutes

Open Google Cloud Billing Reports and filter by SKU ID. Paste the six SKU IDs listed above into the SKU filter. The resulting line items show your current monthly spend at the affected rates. Multiply by 2 (for North America) or the appropriate regional multiplier to project your post-May-1 cost at list price¹.

This is a read-only operation in the Billing console — no infrastructure changes, no risk. Do it today.

Contract Protection: Fixed vs. Floating Discounts

Your exposure depends on contract structure. Fixed-price contracts are protected from list-price increases until renewal. Customers with floating discounts — discounts expressed as a percentage off list — may see immediate impact when list price rises¹.

Google recommends contacting your account team to review the specific terms of your contract¹. If you are on a floating discount and your contract renews after May 1, you should initiate that conversation this week, not after the bill arrives.

Cost-Reduction Playbook, Ranked by Effort

1. Enable Private Google Access (zero code changes)

Private Google Access (PGA) eliminates egress charges for traffic to Google APIs by routing it over private VIP ranges rather than public internet paths. DNS must resolve googleapis.com to the 199.36.153.x range, which happens automatically once PGA is enabled on your subnets. No application code changes are required³.

2. Tune Cloud CDN Cache Hit Rate

At an 80% cache hit rate, Cloud CDN reduces egress spend by approximately 72%: a 10 TB/month workload drops from roughly $850/month to roughly $234/month³. The primary levers are cache-control headers — s-maxage=300 for edge caching on static assets, short TTLs for user-specific responses. This requires application-level changes but no infrastructure migration.

3. Migrate to Verified Peering Provider

Google’s official recommendation for Direct Peering and Carrier Peering customers is to migrate to Verified Peering Provider (VPP)⁴. VPP offloads provisioning, network operations, capacity management, and troubleshooting to the provider, and unlike Direct Peering, it includes SLAs⁴.

Gold-tier VPP providers — meaning physically diverse connectivity across multiple metro areas — include Verizon, Lumen Technologies, AT&T, Arelion, Vodafone, Deutsche Telekom, and KDDI⁵.

4. Dedicated Interconnect for High-Volume Egress

Dedicated Interconnect egress costs $0.02/GB, compared to $0.08–$0.23/GB for internet egress routes — a 4–10x gap³. At sufficient volume, the fixed provisioning cost of Dedicated Interconnect is amortized quickly, and the unit economics remain favorable even after the peering price increase. This is the highest-effort option on this list, but the most durable for teams with predictable, high-volume egress.

What Verified Peering Provider Actually Is

VPP is a managed connectivity service where a qualified network provider maintains the physical peering relationship with Google’s backbone on your behalf. From a billing perspective, egress flows through the VPP rather than through a self-managed peering port. The provider handles all operational complexity: capacity planning, fault isolation, and SLA enforcement⁴.

The gold-tier designation means the provider has diverse physical connections in multiple metro areas, which matters for redundancy in production architectures⁵.

What VPP does not do: publish its pricing. Every VPP engagement is a commercial negotiation with the provider. Google’s guidance is uniformly “contact your account team,” which means the discount — if any — is entirely a function of volume, relationship, and timing. Evaluate VPP alongside Dedicated Interconnect, not as a guaranteed improvement over it.

The Bigger Picture: The NA Peering Discount Is Effectively Gone

The new North America rate of $0.08/GiB matches the existing floor for internet egress via the Premium Tier¹. That means the historical discount for peering — the reason enterprises set up Direct Peering or CDN Interconnect in the first place — no longer exists in North America at list price. Any cost advantage now depends entirely on negotiated contracts, VPP arrangements, or architectural changes that reduce total egress volume.

That is the context behind Google’s stated rationale of “align[ing] pricing with the value and performance of the services”¹. The practical effect is that peering is now priced the same as standard internet egress in the region that generates the most GCP traffic.

FAQ

Does this affect my Cloud CDN bill if I use Google’s own CDN, not a third-party? No. The affected SKUs cover CDN Interconnect (third-party CDN peering), Direct Peering, and Carrier Peering. Standard Cloud CDN egress from origin on the Google-managed path uses different SKUs and is not part of this announcement¹.

If I’m on a fixed-price contract, am I safe until renewal? According to Google’s guidance, fixed-price contracts are protected from list-price increases until the contract renews. Floating discounts — expressed as a percentage off list — may not be protected¹. The specific answer depends on your contract language; your account team can confirm.

Is there a deadline to engage the account team about VPP? Google has not published one. But given that May 1 is eleven days away and VPP involves physical network provisioning, any migration will not complete before the price change. The near-term priority is auditing exposure and protecting contracts; VPP is a medium-term architectural option⁴⁵.
