Internet broken in parts again


[link to this post]
 
Previously.... http://forums.thinkbroadband.com/general/f/4590933-i... which fixed itself but may have returned.

I canít access Netflix.com, ispreview.co.uk or DuckDuckGo.com. ee.co.uk is working (it wasnít last time this happened). Some other sites seem slower than usual even for a 3Mbps connection. I can reach this site as usual, the BBC is fine if slow to load.

Last time pings showed timeouts, I havenít been able to ping yet (can an iPad ping?) but I expect the same result.

One interesting difference is I can reach my ISP Zen, which failed last time.

So anyone else see this? Any other ideas before it mysteriously fixes itself?!

Yes, can reach 8.8.8.8. Current DNS is Zen's default, haven't tried others today because I don't think its a DNS problem. I can resolve the IP address of Zen for example as seen in this ping attempt. I did try diffferent DNSs last time this happened and that wasn't the solution then.

Many hosts are configured to not send a response to a ping packet so the fact you are getting timeouts from pinging zen.co.uk doesn't really mean anything.

Over the last couple of days, been seeing some odd behaviour also, worse has been android mobiles reporting no internet. Many timeouts accessing sites, but not consistent. Restarted all internal network devices, and rebooting phones, with little but inconsistent results. This using different ISP - John Lewis on ADSLmax, and opendns.

Using mobile data from the phones (three network) works fine.

Tracert is basically pinging each router in the route 3 times, starting with your own, then stepping/hopping to the next one.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - AAISP Home::1 80/20. 200GB. Sync 70370/12780Kbps @ 600m. BQMs - IPv4 & IPv6

I should have also ask if this is happen with other browsers, Firefox, Chrome, Opera.

Sometimes doing some cleaning up and deleting everything in the browser catch can fix things.

I dont have iOS anything but from Andriod there a lot of free app's on the store that can do networking things like ping-ing.

You could try a ping the web site domain, this can be using a different IP from just domain name ie :
ping www.netflix.com
