This morning I suddenly lost my connection to the web while I was

Mail still worked, news still worked, but the web connection did not.

I reset the router, rebooted my computer, but still nothing.

I wondered if it was a browser fault (I use Firefox) so tried Internet
Explorer. It too could not connect, but offered to run diagnostics.
This is what was found:

DNS failure

I haven't read the entire thread, but this is mostly likely your
problem.

Your default Domain Name Server is down or can't be accessed. When you
can't access "The Web" with your browser, but mail, ftp, etc work
(they don't use DNS), that's where I'd start the troubleshooting.

WRONG. Anytime you use a hostname (host.domain.tld) to specify a host,
like for an e-mail or ftp or "etc" server, DNS gets used. Humans like
names. Computers demand numbers. How many times have you encountered a
user that specifies the IP address address for their e-mail server when
configuring an account within their local e-mail client? Look at your
own e-mail config in whatever local e-mail client you use. Did you
enter a hostname or an IP address? Unless you do the DNS lookup when
configuring the e-mail account in your e-mail client, you don't get that
info from the e-mail provider as they give you hostnames. How many web
pages have you visited where absolute references (non-relative or just a
path under the current location) to sources in a web page use IP
addresses instead of hostnames? If DNS were unusable to the OP, he
wouldn't be doing e-mail or newsgroups. If the OP were having to use IP
addresses for everything, he would've mentioned it and maybe how he got
those IP addresses.

Not 100% true. I believe the Eudora email client uses DNS once to lookup
the IP address of the email server(s) when it first accesses them. From
then on it uses that stored IP address. There were times when I have ported
my domain to new hosting and the browser always finds the web site once it
is back up. But the email program seems to continue to access the old
servers until I do something to make to do a DNS lookup again (like restart
it).
