Overview

Internap began as a networking company and later supplied colocation, hosting, cloud and media delivery. Its proprietary CDN grew from VitalStream, acquired in 2007.

This entry covers the historical Internap CDN. The continuing INAP cloud business became HorizonIQ in January 2024 and joined Summit in 2025. Existing CDN customers should check their current service and support arrangement before migrating.

Network

Keep the networks separate

The old CDN, internet-connectivity business and hosting facilities had different scopes. The Unitas transaction included network assets and MIRO; Evocative’s agreement covered colocation facilities and related services.

HorizonIQ now lists hosting regions across the Americas, Europe and Asia-Pacific. That combined successor footprint is not an inventory of Internap cache cities. No current legacy-CDN map is inferred from those addresses.

Past features

Historical CDN

VitalStream delivered streaming audio and video, with advertising selection and insertion, storage and professional services. This historical media portfolio is distinct from MIRO’s internet-route optimization.

Current successor infrastructure

HorizonIQ offers private cloud, bare metal, storage, networking and infrastructure security. For a CDN replacement, check the security controls on that delivery service separately from HorizonIQ’s hosting products. Test required protocols, purges and log delivery against the selected replacement.

Service status

Confirm which business and operator now serve each legacy agreement. CDN delivery, internet connectivity and colocation may follow different paths.

Inventory DNS, certificates, origin routes, cache policy, streaming formats, logging and any advertising workflows. Obtain a current service statement and test the replacement before moving traffic.

Budgeting for a replacement

Get a current replacement-provider quote for CDN delivery. HorizonIQ’s server, private-cloud and storage prices cover infrastructure products, not an equivalent CDN delivery plan.

For replacement budgeting, enter a current CDN’s USD quote in the calculator and separately account for origin hosting, bandwidth, storage and security. Review any existing contract with its actual current operator.

Historical integrations

Current HorizonIQ documentation covers the Compass infrastructure API: server actions, network information, billing, certificates and support. The Documentation link leads to that successor API reference.

For the CDN integration, request the current API and migration instructions from the account operator.

What to know

Use this entry to understand an older Internap or VitalStream agreement and separate its media-delivery dependencies from infrastructure hosting. HorizonIQ may be relevant as a current origin provider, subject to its present service terms.

Planning a replacement

For a legacy CDN account, find the current service and support contact before migrating. Successor hosting products are a separate purchase; check media formats, advertising workflows and delivery controls against the replacement CDN.

History

Network and media roots

Internap was founded in Seattle in 1996. It completed the VitalStream acquisition on February 20, 2007 for approximately $214 million, including transaction costs. Previously it resold third-party CDN services.

Restructuring and successor businesses

INAP emerged from Chapter 11 in May 2020 as a private company. Unitas acquired its network-business assets in May 2022. Evocative announced a separate agreement for nine data centers later that year.

INAP completed another restructuring in August 2023, rebranded the cloud business as HorizonIQ in January 2024, and HorizonIQ’s acquisition by Summit was announced in December 2025. For a legacy CDN account, check its current operator and support arrangement.
