This morning I had an approx 30 minute downtime in ADSL from 9:15-9:45am, where 2 different ADSL modems both reported Line State = Down.
(I had 2 adsl modems to test)
With Xnet naked broadband.
Called Xnet, just got the usual response, check modem, cables, line, restart.
Previous to this outage, typical line rates were:
(using 2 different modems, Dynalink RTA1320v6, & an old Conexant PT-3812)
Downstream: 7500 Kbps
Upstream: 750 Kbps
And typical speed tests using www.consumerspeedtest.org.nz resulted in approx:
Down: 6.5 Mbps
Up: 0.65 Mbps
After the 30 minute outage, DSL came back up, but with slower line speeds.
Both modems now report approx:
Downstream: 5180 Kbps
Upstream: 704 Kbps
And new speed tests using www.consumerspeedtest.org.nz result in approx:
Down: 4.5 Mbps
Up: 0.60 Mbps
So an approx 30% drop in downstream line rate and speed performance.
This is on the Spotswood exchange in New Plymouth.
Anyone have any idea's?
Have logged an issue with the Xnet help team, still waiting to hear back on their thoughts.
One possibility is that Telecom/Chorus techs are changing cabinets in the exchange for ADSL2+ rollout.
But this exchange is not due until June 2011, according to www.telecomwholesale.co.nz/maps
The only reason I'm raising is this because I work from a home office, and use VPN connections to both USA and London, for work, and drop in speed is slightly noticable when transfering work files around.
