Cannot access a certain web site. How to determine if the problem is in the computer of if the web site is not working?

My computer is a HP z230 workstation running Windows 7 pro.

Each time I try to read the web site, my browser (Firefox v58.0.2) tells me it cannot connect to this web site.  I have tried connecting using my other Windows computers and none of them will connect to this web site.

When you cannot connect to a certain web site, how do you determine whether the problem is in the web site or in your computer or some place else?

What software or tools do you use?

Please give me detailed answers.  I am not a network expert.

I've just confirmed it's a problem with the site so nothing you can do about it.

Look here >>

Windows Secrets is a very popular site so will likely self-correct itself soon.

When you cannot connect to a certain web site, how do you determine whether the problem is in the web site or in your computer or some place else?

A simple and quick way is to use this resource -  (Just bookmark it for future use)

Enter the URL of any website you're having problems with and the above resource will tell you if it's down for everyone, or just you.

Once you've confirmed it's not the site - then you can start suspecting other causes such as your own machine or Internet Service Provider. There are far too many possibilities to list, so just ask for help if a site won't open that the above resource reports as working.

Hope that's helpful.

Hi Don,
I use two sites in these circumstances. One is the site that Andrew recommended. The other is this:

Here's what it says:

to the question
1) use nslookup to see whether the site resolves. nslookup 
a. if the site does not resolve, it is an issue with the domain's registration taking into account you are able to access other sites
b. ping the IP that is returned above
2) if you get a timeout error, failure to connect, but can access other sites, the issue is outside your control and there is no need to spend any more time on the matter

The short answer, the issue is with your computer, network, connection to the internet when you can not access anything external.
In this circumstance, check whether you can ping as an example (google DNS)
your issue might be that your browser is configured with a proxy that is no longer responding, or misdirected to a proxy... confirm browser settings for proxy is direct connection or if proxy required, is pointing to the correct ....

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

In addition to what arnold has mentioned, I would recommend also having access to another network available, even if that's something like connecting your laptop to your mobile phone for internet connectivity. This allows you to determine whether your IP address might be blocked from the website. (The sites that Joe and Andrew provided would assist in this exact same scenario, I just provided a more manual mechanism of doing the same thing)

Just got this in email from Windows Secrets.

As I mentioned in my first post, the site is down. A restoration is in progress. See below.

Hello to subscribers –

First, we’d like to apologize for the delay in reaching out. We had hoped that our service interruption would be only a day or two long, and we could resume publication last week. We were wrong.

Here’s why you haven’t gotten a newsletter and you can't access the site: There was an unprecedented hardware failure across several systems.

The IT department has been working to remedy the failure and restore the affected sites from backups. We don’t have a timeline for restoration – but we don’t want you to think we’ve completely disappeared.

You’ll receive double editions of the newsletter after the IT department has restored the site.

Again, our apologies for not reaching out sooner. We’ll keep you informed of future developments.

From your link...

As for… I haven’t a clue.

How was that supposed to help? LOL

Edit: I just saw further down in comments that they've now realised what the problem was at the above link too. Just struck me as hilarious when I clicked the link and found that all "Woody" had to say was
"I haven't a clue" Hahaha  Good old Woody
