Moved to Spark Ultra Fast Fibre MAX mid January and has been fine until the 8th of Feb. Since then upload has been (relatively) crippled to 30Mbit/s inside NZ, 8Mbit/s OZ, 1Mbit/s US, <1Mbit/s Europe (speedtest data).
Most noticeably, I could saturate upstream with my NAS backup to Amazon cloud drive with 5 connections uploading at 100Mbit/s each, now I won't get more than 1Mbit/s per connection.
The helpdesk haven't been much help - power off ONT, power off router, wait, power on ONT, power on router. No change, repeat this time resetting router to factory default. I'm in Christchurch. Used both Spark Huawei router and an ASUS RT-AC87U.
Any ideas? No wifi being used, QoS is off. It's driving me a bit nuts.
