SA-based national ISP Internode has slashed the price of its high-speed “Ultra SHDSL” Internet connections for business by up to 50 percent.

The Ultra SHDSL service delivers fully symmetric ­ same speed up or down ­ broadband at up to four megabits per second.

The flagship Ultra SHDSL plan, operating at 4Mbps, drops from $2450 to $1200 a month. Other plans are available starting at $300/month.

The new pricing follows a new, cheaper deal Internode has inked with Optus, which provides the wholesale service.

 Internode also offers Extreme SHDSL in parts of Sydney, Melbourne and Adelaide at up to 40Mbps. A 10Mbps connection costs $1000 a month.
