Why is Google.com both UP and DOwn

Can you go here?

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

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.

25

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.

1. NO

TalkTalk online chat told me that IE and FIrefox can reach Google, my ISP has not blocked it

I cannot reach Google in any way

2. YES

Palemoon installed (default) cannot get there

Palemoon Portable cannot get there

CMD.EXE PING cannot get there

Samsung TAB2 Android Tablet with a Dolphin Browser has also lost contact with Google and Gmail before I switched on Yesterday morning,

and this is dependant upon WiFi to the same Router and ISP and DNS

3. No, I can try that when I close Palemoon, though I would be surprised if that helped PING or Dolphin :)

4. I actually flushed the DNS cache yesterday without success.

I Rebooted my Modem/Router this morning and got a new dynamic IP address - but this did not fix the problem

It occurs to me that I could have received cache corruption between yesterday's flush and this mornings reboot,

so I have just repeated the flush and I still cannot PING to Google.

Right now I am experimenting with NameBench,

I just wish I could make it focus upon resolution of Google.com,

it takes so long waiting for it to test hundreds of resolutions on thousands of DNS

Can you reach google in safe mode with networking? This could eliminate 3rd party interference.

Until yesterday my Android Tablet was still receiving my Gmail,

and I doubt that malware would strike both Windows and Android at the same time.

I think Malware would be more interested in blocking A.V. sites than in blocking Google

I would expect a hardware fault to block more than Gmail and Google

My P.C. software has not been updated this week

My Android has not been "Rooted" and has antivirus etc that is on automatic update,

but I am not aware of any capability for it to modify the password protected settings of the Router and block my PC from Google.

Fun Fact

Used StartPage to search for MalwareBytes

Clicked on the Top result to download from

www.malwarebytes.org/

This was a Google sponsored ADD which my DNS failed to resolve.

Clicked on the first result below sponsored Adds

www.malwarebytes.org - View by Ixquick Proxy - Highlight

That took me to the intended Download.

I love lxquick Proxy :D

Thanks.

Building up a Todo list for later this afternoon :-

Clear Browser cache and cookies ;

Start in Safe mode with Networking and try for Google

SOLVED

Cleaning browser cache and cookies did nothing

Starting in Safe Mode with Networking also failed to find Google.

Google's NameBench did not help at all.

The DNS BENCHMARK from GRC.COM gave the answer.

My Primary DNS was 62.24.128.18

and this is no longer a DNS server.

This is now owned by TalkTalk - it was NOT owned by TalkTalk when I first selected it.

Consequently my secondary DNS was the only working DNS at 213.253.136.17

and this has forgotten where Google is.

By replacing TWO bad / broken DNS with a solitary GOOD DNS at 199.2.252.10

I now have full access to Google Search and Gmail and via PING.

Tomorrow I choose a secondary DNS

If your ISP can configure your settings on their end one would've thought they could've taken a peek to see if anything was wrong, I know my ISP CenturyLink will do that to make sure everything is correct.

At least you've figured it out, those network settings can be a complete pain when they go bad.

Yea DNS issues are fun.

Good to see you figured it out
