Same results with Portable Palemoon, so I do not think I need to flush DNS caches etc.

 

Is it possible that TalkTalk, my ISP, is mistakenly blocking Google.com instead of PirateBay :o

I was offline for doctors appointment.

Now returned.

 

Google is dead at my router.

 

Ping test:-

 

C:\Users\Alan>ping google.com
Ping request could not find host google.com. Please check the name and try again.

C:\Users\Alan>ping www.google.com
Ping request could not find host www.google.com. Please check the name and try again.

 

I have now tried a Samsung TAB2 Android Tablet with a Dolphin Browser.

This also has no access to Google via Wifi to my router,

and it has no independent 3G/Mobile access to the Internet.

 

This proves a totally different browser on a different platform is unable to reach Google.com via my router and broadband connection.

 

TalkTalk (my ISP) have access to Google via both I.E. and Firefox.

 

Logging in to my Netgear Router I find

primary DNS = 62.24.128.18

Secondary DNS = 213.253.136.17

 

Ping test on my DNS :-

C:\Users\Alan>ping 213.253.136.17

QUESTIONS :-

 

1.

Is it possible that there is some filter blocking my local broadband connection via local "OpenReach" Telecom wires ?

 

2.

Is it possible that my Router always gets the WRONG answer from one DNS and fails to try the other DNS ?

 

3.

Is it possible that both DNS have been poisoned or misinformed about Google ?

 

I forget the DNS locations but I think I selected one about 100 miles to my West and one about 100 miles to the South to obviate any medium scale OpenReach calamity.

 

Regards

Alan

 

P.S.

http://public-dns.tk...server/gb.html� reports :-

213.253.136.17 dns-cache1.lon.as5587.net London 9.5.0-P1 4 hours ago Valid valid

Unfortunately 62.24.128.18 is NOT shown on this site

which suggests that it is not a viable public-dns, even though I can PING it.

 

Perhaps 62.24.128.18 is broken and only 213.253.136.17 is working but has forgotten the IP address of Google :o

Thanks

 

I remember difficulties both in selecting geographically diverse servers and then in setting the router to their IP's.

I will enjoy freedom from spam for the rest of today before I go down that route.

 

On the bottom of that site are 6 columns, and the fourth one has the header

DNS Server Database

Under this are 6 entries, only 5 of which take less than one second to present a long list of names.

The odd one out is Google DNS which takes 3 or 4 seconds before responding with

Google DNS

 

Google has just recently launched their very own public DNS servers called "Google Public DNS". The idea behind Google's DNS servers is that they want to make the internet faster, safer, secure, and more reliable for all internet users. Lots more information will be coming to whatsmydns.net very shortly but in the meantime for those who are a little more tech savvy you can get started using Google's DNS servers straight away.

Primary DNS Server: 8.8.8.8

Secondary DNS Server: 8.8.4.4

 

The thought occurs that perhaps Google has just made a change and broken something vital. :angry:

Alan

The google dns entry at the bottom of the page is more or less instant for me Alan.

 

Have you tried clearing your cache?

 

Also try doing a cmd prompt and then

 

ipconfig /flushdns

 

it quite often works in cases like this.

Google search engine is NOT accessible to me,

BUT the StartPage Search engine DOES work and gets my answers from Google.

I have just used Startpage to search for the two words Google Down and restricted the results to U.K. and last 24 hours.

Result

http://community.babycentre.co.uk/journal/p_timer/1608321/is_it_just_my_computer_or

The Admin there reported Google was gone 19 hours ago

just me then!

This webpage is not available

The webpage atwww.google.co.uk/might be temporarily down or it may have moved permanently to a new web address.

Error 15 (net::ERR_SOCKET_NOT_CONNECTED): Unknown error.

 

Admin of this great group :-D

and 2 hours later

yay! it's back!

 

Admin of this great group :-D

 

I am guessing that both my DNS are still going to the old IP address.

I hope they do their homework tonight :)

I first decided that my Android Tablet would not have the simultaneous need to have its DNS flushed,

but then with nothing else to do I tried that just incase it might also affect a cache in the router,

but again no benefit.

 

I do observe that the link you gave me shows

Primary DNS: 62.24.199.13

Secondary DNS: 62.24.199.23

Tertiary DNS: 62.24.128.18

Additional DNS: 62.24.128.17

I choose 62.24.128.18 on the basis of ping delay speed.

I was not aware at that time it was a "third class" server

Is it possible that 62.24.199.13 knows where Google is now,

and tomorrow it will tell 62.24.199.23

and the next 62.24.128.18 will update ?

I'm sure if you used IE for 30 seconds to test your connection, the death toll would be pretty minimal.

I would rather install Chrome than unleash IE :o

 

But since my initial reaction I thought of Android with the Dolphin Browser and found that this also cannot find Google.

 

Incidentally, IE is a bad choice according to the Service status of my ISP

http://www.talktalk....service-status/

03/04/2013 16:27 Open - Broadband status Telephone status A Microsoft Internet Explorer 10 upgrade is causing problems for some customers accessing Tiscali Webmail (for more information please visit http://help2.talktal...when-using-ie10).

Sometimes just rebooting your modem can do the trick if the problem is ISP related.

Thanks - I will try that.

Normally my dynamic IP address is only revised after several hundred hours,

I notice that the Router stats show it has been up for 32 hours 18 minutes,

i.e. I was allocated a new IP address at about 3:00 a.m. on the morning that Google vanished

 

SUPPLEMENTARY :-

 

I powered down the Netgear DG834G Modem Router for 2 minutes,

and after I powered up I saw a new IP address and my download speed increased by 30%

(with Noise margin reduced from 8.6 dB to 5.6 dB)

 

Unfortunately Gmail and Google are NOT coming back to me,

and PING GOOGLE.COM still gives :-

Ping request could not find host google.com. Please check the name and try again.

 

I can choose alternative DNS addresses,

but it is so tedious typing in the numbers and then waiting for a shut-down-reboot to see if I am lucky,

especially if the fault is not in the DNS but in my router or in the OpenReach/Telecom broadband link between my router and my ISP

 

I really would like to have an instant test of whether a specific DNS is able to resolve Google.com for me.

Is there any tool that will help me.

 

Regards

Alan

I would have made a passive aggressive phone call to my internet service provider by now.

I contacted them yesterday and they confirmed that Firefox and I.E. were accessing Google.com and not being blocked.

I may well start shouting tomorrow - but at the moment I suspect the DNS I am using.

 

I have just downloaded (not from Google) Google's Namebench tool.

For my existing DNS this reports that Google and Twitter are hijacked or wrong on 11 test DNS, e.g.

 

Does this seem to be business as usual, or is there some serious hacking in progress ?

Can you go here?

 

https://www.google.co.uk/

No, that fails also.

 

I also tried pinging them

C:\Users\Alan>ping google.co.uk
Ping request could not find host google.co.uk. Please check the name and try again.

C:\Users\Alan>ping www.google.co.uk
Ping request could not find host www.google.co.uk. Please check the name and try again.

C:\Users\Alan>ping https://www.google.co.uk
Ping request could not find host https://www.google.co.uk. Please check the name and try again.

C:\Users\Alan>ping http://www.google.co.uk
Ping request could not find host http://www.google.co.uk. Please check the name and try again.

Although the end results are the same, the time taken is repeatedly but drastically different :-

3 Seconds for ping google.co.uk

1.5 Seconds for ping www.google.co.uk

0 Seconds for ping https://www.google.co.uk and ping http://www.google.co.uk

So lets get up to date here Alan.

 

1. You can reach google with IE and Firefox

 

2. Palemoon (your default) cannot go there.

 

3. You have cleared out all your browser cache and cookies.

 

4. You have not yet tried flushing your dns cache.

Could be anything from your ISP (do they ever fess up that it's their fault usually not), failing hardware modem/router and they do die at some point (think lightening and power surges), or some malware possibly on your computer.

 

If you've recently switched antivirus' or updated a pre-existing one to a new version some (perhaps most nowadays) have a network protection driver/filter that can sometimes interfere with websites loading or working correctly.
