Over the past few weeks, I have noticed times where sites go offline or are unreachable. My own site has been experiencing this, with customers reporting outages or intermittent connectivity. Even WebmasterWorld was down about an hour ago for maybe 10 to 15 minutes. Of course my dedicated hosting provider denies any outages, yet the reports keep coming in.

I am wondering if this has anything to do with IPv6. It seems like the problem is at the router level, not the servers. Anyone else noticing this or am I just hallucinating?

I've been online daily since nearly the dawn of the internet, so I can usually tell what's causing a problem like this.

Thanks!

Well, I have one or two customers who still insist my site is down, yet Alerta, AlertSite and my own browser begs to differ. I run a dedicated server and my hosting company (layered tech) swears there have been no connectivity issues. Meow! - (what was that?)

I think the word "internet" is actually short for "intermittent network" :)

Failed routing issues happen all the time.

Tell your customers to run tracert from the command line, it'll tell them where the internet is broken between their IP and your server.

To prove your site it up, direct them to any CGI proxy site like Proxify or some internet tool site like DNSSTUFF where they can see other sites can connect to you, your site is up, and their connections are junk.

They aren't just missing your site, they'll be missing others as well.

They'll need to contact their ISP about fixing it.

You're probably right Bill..but ..

:) suggesting to most windows users that they "open a command window" and type anything at all, is like telling them that they can perform their own eye surgery, or dentistry..with the aid of a mirror and a pocket knife..

OpenDNS can be a bit of help sometimes.

One of them just wrote me back and said he rebooted his home router and now it works...geeze. At least he apologized for calling me a scam / ripoff site. Half cocked customers, gotta love em.

One other thought is that with the Solar max approaching, we might expect wide spreed outages. This is the first time that our modern (copper) internet infrastructure might experience larger/peak CME events.

Surprised they let you know!

That's the beauty of tracert, they would've found out it died in the router immediately.

Just wait until all the radio and TV satellites go into safe-mode, if they do, and we lose tracking on them and they never come back.

People think they'll be safe with cable vs satellite yet don't realize cable also gets satellite feeds, rude awakening coming some day.

TV will look like it did in the movie Independence Day, if there's any TV left.

The internet will then crumble, what's left of it, as all the people desperate for TV will hit Netflix and HULU all at once and bring the backbone to an overloaded screaming halt.

At which point, customers will really think your site is down :)

My local big name ISP regularly changes DNS servers with no notice. One desktop we have Google's public DNS (8.8.8.8) hard coded in for those times when their DNS is bonkers (too often).

If they make a change but our IP lease is still valid (many hours to go) there is a time where only stale DNS attributes are still propagated to downstream machines. That's most likely why the router reboot fixed the complainer's issue.
