Squarespace Help are asking for information from people suffering from slow performance. Here's the details. Answers in the comments [or by email] please:

I'll need to know your visitors IP address. To find it, visit this site:

http://www.whatismyip.com


I'll also need them to do a traceroute. If you're using a Mac, open Spotlight by pressing Command+Space and open the Terminal.

Then, type traceroute and a space followed by your domain name. Press Enter.

If you're on a PC, go to Start > All Programs > Accessories > Command Prompt.

Then, type tracert and a space followed by your domain name. Press Enter.

Once you've done that, you'll need to do two more traceroutes: one for CNAME and another for IP

Update the CNAME and IP for the customer's platform:

CNAME:
five.squarespace.com

IP
65.39.205.54

When all three traceroutes are done, copy everything in the Terminal or Command Prompt and paste it into your reply along with your IP address.

Thanks.
