[RndTbl] Shaw now blocking SMTP port 25

[Sean Walberg]

I agree, I thought Ottawa had an anycast node from the ISC (f) root
server...

[root at wpgnetsvc02 ~]# traceroute f.root-servers.net
traceroute to f.root-servers.net (192.5.5.241), 30 hops max, 40 byte packets
...
 9  gw-isc.torontointernetxchange.net (198.32.245.23)  58.612 ms  22.422 ms
22.475 ms
10  f.root-servers.net (192.5.5.241)  23.249 ms  23.457 ms  23.758 ms

I don't know about any of the gTLDs (.com, .org), but the ccTLD for .ca is
in Canada, I don't know the locations:

[root at wpgnetsvc02 ~]# dig foo.ca @f.root-servers.net
...
;; AUTHORITY SECTION:
ca.                     172800  IN      NS      CA04.CIRA.ca.
ca.                     172800  IN      NS      CA05.CIRA.ca.
ca.                     172800  IN      NS      CA06.CIRA.ca.

ca.                     172800  IN      NS      CA02.CIRA.ca.
ca.                     172800  IN      NS      CA03.CIRA.ca.
