Indonet's Cyber Bld DC occupies a suite in Gedung Cyber 1, the tower on Jl. Kuningan Barat in Mampang Prapatan, South Jakarta 12710, that became Indonesia's first carrier hotel. PT Indointernet Tbk sells shared colocation and dedicated cages from that space; the block is managed by PT Karyagraha Nusantara and holds the suites of at least eight other operators, so a tenant here is buying into a shared address rather than an Indonet building. The address is the point: APJII runs IIX and OpenIXP from the same tower, which is where Indonesian domestic traffic meets. Indonet commits to 99.9% availability and describes UPS strings with at least twenty minutes of autonomy, a PLN-to-generator changeover inside ten seconds, precision cooling and FM-200 suppression. Control of the company now sits in Hong Kong: Digital Edge entities held 92.1% of PT Indointernet at the end of January 2026, having bought out the founding shareholders in December 2023, and are taking it off the Jakarta market. Rempoa, in Tangerang Selatan, is Indonet's other data centre.

Frequently asked questions
Which company manages Gedung Cyber 1?
PT Karyagraha Nusantara. Indonet is one occupant among many - at least eight operators keep registered suites at Jl. Kuningan Barat No. 8 - so the building is a shared carrier hotel rather than an Indonet asset.
Which exchanges are reachable inside the Cyber Building?
IIX and OpenIXP, both run in the tower by APJII. That concentration of domestic Indonesian traffic is the main reason tenants take space at this address.
Who controls PT Indointernet today?
Digital Edge, through two Hong Kong entities holding 92.1% between them at the end of January 2026. Digital Edge bought the founders' remaining shares in December 2023 and is taking the company private.
What backup does Indonet describe for the suite?
UPS strings rated for at least twenty minutes of autonomy, changeover from PLN mains to generator in under ten seconds, precision cooling and FM-200 gas suppression, against a published 99.9% availability commitment.
Which other data centre does Indonet run?
Rempoa DC at Rempoa Raya in Tangerang Selatan, south-west of Jakarta. The rack counts Indonet publishes belong to that site, not to the Cyber Building suite.
