Hi - anyone else experiencing congestion since about 3.30pm today?
Basically unusable for both domestic and international sites, and voip,2talk Auckland server garbled.

Continue to experience more instances of VF Broadband congestiing and slow!
Have the new Cisco DOCIS cable internet router and 50Mb/2Mb service but access upgrade does not help these recurring network events.

Cheers

Where in Christchurch and have you logged a fault ticket via the phone also provide example speed to local server please?

Thanks

Edit: No speedtesting over WiFi on LAN cable into modem

Thanks for response Jonn - Hoon Hay area of Chch -

Cannot tolerate the very long VF CS Queue - so sorry will not no log a ticket.

await a fix I guess to current really poor service...

Generic response, latency and slow network will be in same scenario as current multiple Kapiti Cable issues posts

regards
Peter

You are best to log an official fault ticket please via a call in, Note down that ticket number! If you don't want to that is your call

John - yes I would normally but spent toomuch time in VF CS team queues holding and mucking around, if not fixed tomorrow I will log one.

FYI - - Speedtest basiaclly not working, Chch VF site will not respond on speedtest (error message) - a.
Auck VF server 24ms ping with 70 to 90Kbs download that will not complete test.

Am posting on forum via Spark 4G mobile network

There's a sizeable chunk of west Christchurch with no electricity right now, including my house. Not sure if that has any effect on the areas that have power.

(Edit: our electricity is back, speedtest is showing the expected speed for our plan, youtube working fine. Just went to Cisco modem ouselves, our speed should switch from 15/2 to 50/2 overnight.)

Thanks for your update, anyway I have service back now, unlikely power outage may impact, but poss I guess, I think VF ex TCL fibre North should avoid that area from my place?

John - FYI my gut feel is these newer Cisco Docis 3 routers are somewhat flakey? The old Motorola surfboard was rock solid, this cisco unit seems to hang sometimes and has slow/delayed initial IP response to servers/sites, start voip calls. i would go back to the old one if I could!
That's my gut feel anyway, or maybe its just the IP backbone?!

When testing speeds on cable please use http://www.telstraclear.co.nz/customer-zone/speedtest/.

This way you test your line mostly, instead of overseas servers out of Vodafone's control.

You seem to think there's a line problem or something with Vodafone - no indication yet it's an international traffic problem, so if you test using that site you will know a bit better of the true line conditions.

Also the Cisco modems are pretty good - have had one here for years now and no problems. VoIP call initiation may be impacted by your router - was it supplied by Vodafone or you bought yourself (do not confuse the modem and router, which are two separate pieces of equipment on HFC networks).

Thanks to those who have given there replies/info on Chch performance. The problem lasted about an hour or 2, may have been a localised Ex TCL Cable network cabinet issue in my area (Hoon Hay Road/Lower Cashmere)?? Anyway 2 resets of my VF Cisco Cable Modem and my own router VoIP ATA, all returned to BAU.

Maurico - My error in using "router" to describe the Cisco Docsis cable Modem, just using a generic term in a sloppy way I guess. My configuration, Cable Modem, 100Mb Router and Linksys Voip Adapator having been doing a solid job for around 10 years in varying upgraded formats - so no issues there. My feedback is one of "user gut feel" re the new Cisco Docsis cable modem unit installed late last year, replacing the original Motorola surfboard modem. It seems to me that packet/service/session start requests have an initial very small lag that was not there before. e.g. having to repeating the first words of a 2Talk Voip local call, or double clicking Yahoo mail client in my browser to open it up. slower page request starts??

The whole performance thing may just be general VF network performance degrading - my user experience: My assumption is this is an impact of more/combined VF/TCL/Ihug customer base on the rationalised backbones and servers, inter ISP peering or lack of, international routing quirks and capacity contention, and VF IP backbone performance on the VF HFC Cable network these days? e.g. I was using my brothers VF service in Timaru over VDSL recently and it was "just overall better" than my Chch HFC Cable performance. it appears the VDSL & Chorus wholesale national backbone responds better to Auck VF DNS servers/Links than my Chch cable fully on-net service?!

Going by forum posts I like quite a few other long term ex TCL VF cable users, who are experiencing on ongoing worsening of response and general overall performance on what was a great network back in the day – frustrating for loyal customers?! I have looked at moving ISP and to VDSL, but would really like to move to Fibre and another ISP, however our Chch UFB supplier Enable is not pushing out to many suburbs fast enough. But this may finally be the year to kiss cable and VF off after years of sticking with it? My 5 cents worth!

Cheers

It's not a "router" it's a cable modem. It acts purely as a layer 2 bridge so it's not possible for it to have any impact at all on your internet performance.

Yes indeed - "a bridge". Without getting into a technical debate, all I am saying is it just does not work as well as it did when it was a Motorola surfboard "bridge" with a 15Mb/2Mb service. Maybe its like the Auck harbour bridge at peak times?!
Maybe just timing of a new modem install along with degrading VF Cable network, local cabinet congested, local metro congestion or Chch Northwards IP backbone, or facets of all??

Net result is combo of degrading performance = grumpy customer = switch of ISP??

Well I thought performance could depend on what data channels the cable modem is locked on to, if the channels were somehow unbalanced some channels would be more congested.
