Question

This site can't be reached

Jan 8, 2020 3:35PM PST

Recently, I've been receiving this message frequently. WHen clicking on a link, this message will appear. When it does, it's not just that site, but usually others that were open. After a few minutes they start again. Some days, it doesn't happen at all. And others, like today it's happened about 10 times already. Thinking it had to do with my internet, I had a long conversation with Spectrum, and they even sent out a tech guy who said it wasn't their fault. Also, had a long conversation with Apple tech and they couldn't solve it. So, doing a little searching, I found that it happens frequently to people. The suggestions were a bit scary for me to try without more information. So, what was said most often is that it has to do with the DNS configuration. I have an iMac, Chrome and gMail and it's only on the iMac that there is any problem. My iPhone and iMac work just fine.. Help greatly appreciated! Peggy

With the new Iran attacks.

I can't say we can count on this working across all machines today.

As to the DNS, did you try that suggestion?

I find some want to avoid this one and may use "other things work OK" as the reason to not try it. In short, you listed very different machines so one machine is not like the other, something isn't quite the same (yes, Sesame Street reference.)

Don't quite understand!

Now, I'm confused! I simply mentioned my other things are working, just not the iMac. No, I didn't try . the DNS as I don't have a clue how to do it or what it is! And what does this have to do with Iran?

Iran is in the news about attacks on the Internet.

As such I am seeing more reports of "can't get to a site" or "not responding". I know some don't read or listen to the news so they may not get the connection.

As to the DNS there are many fine articles about changing it on say an Apple laptop or machine so I'll just drop a link and if that won't do, try another article about this.

Okay, I understand. Regarding the notices of "This site can't be reached"
., I've been receiving them off and on for several weeks. Sometimes I'll go for days without them. It seems it's pretty common with Chrome with all the comments when I asked. I'll try the articles above, Or, i'll call Apple again.
I always like the advice I get here as it seems good. Thanks, peggy

i've been on my computer all day yesterday and today and there have be no " this site can't be reached" problems. None! I've not done anything to my computer, so it seems to me it must be something with my internet provider, Spectrum, altho they don't admit it. I'm not thinking it won't happen again, as it has many times, after a period of working. But it sure is nice to have it working. Any thoughts?

Yes.

Using the ISP DNS is likely what's amiss. Sorry if I don't write much here as it's been done to death.

DNS

DNS is a so-called phonebook of the Internet. It translates domain names to IP addresses so browsers can load Internet resources. Some ISPs can restrict access to certain sites, and changing DNS addresses can surely help in such a case. There are a few trusted and reliable DNS addresses that you could set up on your iMac (you can simply google 'safest DNS in the world'). I'd personally suggest Google or OpenDNS. Once you change it, check if the sites can be accessed. If yes, then well, your ISP is a liar. Good luck!
