I've been using dns4me.net so that my Chromecast can access BBC iPlayer, and it works really well.

I've got my DNS servers set up as 101.98.11.156 for primary and 54.79.3.18 for secondary, as recommended in the dns4me FAQ.  These are meant to be located in Auckland and New South Wales respectively.

I've found that many sites that I visit that use Google services fail to complete loading. My browser shows things like "Waiting for www.google-analytics.com" in the status bar, or "Waiting for maps.gstatic.com".

If I switch to using my ISP's (Vodafone) DNS servers then everything works fine and the pages complete loading ok.

If I do an nslookup on maps.gstatic.com using 101.98.11.156 I get 216.58.220.131 as a result. If I do the same but querying 54.79.3.18 I get 216.58.220.99.

If I do an nslookup on maps.gstatic.com using Vodafone's 203.109.129.67 I get all the following returned: 203.109.178.26, 203.109.178.59, 203.109.178.46, 203.109.178.24, 203.109.178.16, 203.109.178.20, 203.109.178.31, 203.109.178.37, 203.109.178.57, 203.109.178.49, 203.109.178.38, 203.109.178.42, 203.109.178.48, 203.109.178.53, 203.109.178.35, 203.109.178.27

Can you explain what's going on? Does the Auckland dns4me.net DNS server need refreshing or something? As you can imagine Google Analytics and other Google tools are used a lot and so it's a real pain to have all sites that reference it fail to complete loading.

Are any other dns4me.net users also experiencing this?

Hi Murray

I believe you submitted a support ticket with dns4me, and the issue is now resolved. From what we could see Vodafone offloaded requests to google analytics to a Vodafone cache (the ip's returned by your nslookup to Vodafone's dns were there own servers) most likely while they had an issue communicating to googles servers, and because our dns servers return the real addresses for these domains you were having issues connecting to them.

Please let me know if the issue still persists.
