Before I go down the path of contacting Vodafone support, I wondered if anyone here has had the same experience and perhaps resolved the issue themselves or have found that there is no solution and are having just putting up with it.
We've recently had Vodafone fibre installed at our new office on Pitt Street in Auckland City. It's a TelstraClear product, still has their logo on the wall cabinet, telstraclear login etc. While we've found via speed tests that the speed is exactly as advertised (30 down, 10 up), what we didn't count on is the ludicrously long delays when browsing the web.
I'm not sure if it's a DNS issue (seems like it) but quite often, especially during the day and with international sites, it can take sometimes up to 20-30 seconds for a website to start loading after you navigate to it. Certain things seem to work ok (eg google autocomplete) and once the website starts to load it seems ok but there are often some really long waits that makes web browsing a terrible experience. Certain websites seem to fare worse, eg. Pinterest, which seems to load in fits and starts and is basically unusable (as shame as we use it for reference a lot). Instagram is also particularly patchy and erratic when used through this connection.
I checked the DNS entries in our router and they're as they should be for TelstraClear:
Primary DNS:
203.97.78.43

Secondary DNS:
203.97.78.44
We're using a Technicolor TG789vn v3 as supplied by Vodafone btw if that makes any difference.
Thanks for any help or ideas.
Cheers
Luke
