As many of you have probably noticed, currently UPS web site cannot be opened as "ups.com", yet it works fine as "www.ups.com"Opens a new window. It has been like that for several days now. Because of this issue lots of services depending on the functionality provided by UPS web site have been down for quite a while now.
Performing DNS lookup for these two names
> nslookup ups.com 188.8.131.52 Server: dns.google Address: 184.108.40.206 Non-authoritative answer: Name: ups.com Addresses: 220.127.116.11 18.104.22.168
> nslookup www.ups.com 22.214.171.124 Server: dns.google Address: 126.96.36.199 Non-authoritative answer: Name: e13626.a.akamaiedge.net Address: 188.8.131.52 Aliases: www.ups.com ev.ups.com.akadns.net ev1.ups.com.akadns.net ev2b.ups.com.edgekey.net ev2b.ups.com.edgekey.net.globalredir.akadns.net
As you can see, the IP results are completely different. Which probably suggests that the problem is not caused by the setup of UPS servers (e.g. redirecting "ups.com" to "www.ups.com"Opens a new window or somesuch). The problem appears to exist on the DNS side, i.e. the DNS lookup for "ups.com" returns completely nonsensical results.
My question is: who is at fault here? Is this mess caused by UPS web admins? Or is this some sort of unrelated [temporary?] failure of DNS system itself?
