Wow... all of Earthlink seems to be down right now..

[ceagle]

This sure doesn't happen often :P Can't ping it or trace it at all, and needless to say, can't get email.

In checking the tollfree number though, I see that they have discontinued their 24-hour service... >:|
First time I've ever seen that in the roughly 8 years since I've been with them... not a good portent :/
On a similar note, a number of formerly 24-hour stores and food places in our 'burb area have also cut back from 24 .. Home Depot, Kinkos, etc.. what's hapnin'?

ecch.

LH is of course correct.

Most real web sites are using clusters of front end web servers with either load balancers like Cisco's Local Directors or Big IP's F5's (glow in the dark ping pong balls are cool, Mkay? :) to switch traffic at the layer 3 level, or some variation on MS's or *nix web clustering software running on the hosts themselves.

All non-port 80 traffic is > /dev/nul deliberately to minimize hacking, along with other anti hacking filtering and IDS stuffages depending on how spiffy the site is.

Here is a snippet from my traceroute tool (Neotrace):



Note the the edge router, in this case cor02-vl-157.ca-pasadena0.ne.earthlink.net at IP Address: 209.165.101.20 is very much reachable, as is the (presumably from the host name) Local Director in front of the web farm: dir02-vl-296.ca-pasadena0.ne.earthlink.net at IP Address: 207.217.2.125. That LD is on a vlan too, assuming the hostname is sensical.

What is disturbing is the number of dropped packets. There is a problem in the EL backbone network. If it was my 'net to maintain, I'd be on the net god team to fix it. On a hard wired backbone network, the number of dropped packets should be == 0, anything else is bad juju's.

Random small packet loss like I documented above is in my experience almost always a flakey Supervisor Engine in a layer 3 switch. Cisco's chassis switches have a poor hardware reliability record with me, just say I thank goodness for HSRP :-/

Until EL get's their Cisco ducks inna row, I wouldn't be surprised to see more intermittent access issues.
