Match the public A record and response headers to the IP and stack you expect after the move.

How to tell if a site is still on the old host
Check DNS and headers to see which host still serves your site

You can tell which host is serving your site by checking DNS and the response headers. Compare the public A record against the IP we assigned you in the welcome email. If that address still belongs to the old provider, nameservers never fully moved. Next, read the Server header and related fields with curl from a clean network. A browser can mislead you through cache, a hosts file, or a CDN sitting in front.

bash
dig +short example.com A
curl -sI https://example.com | head -n 20

The dig line is the address public DNS is handing out right now. Match it to the IP in your welcome email or the cPanel sidebar. When those numbers disagree, either the nameservers never moved, only the apex moved, or a CDN still proxies the old origin. The curl block shows the Server header, any x-litespeed-* fields, and the rest of the identity. Old hosts keep old headers; our shared platform answers with LiteSpeed.

Compare the A record to your new IP

Replace example.com with your real domain when you run the commands above. That first result is what the public internet uses to reach your site. If it still lists the old address, visitors are not on the new server yet. Once DNS points our way, the nameservers are ns1.logicweb.com and ns2.logicweb.com. Until the A record matches the IP we gave you, the old host remains in the path.

Read headers without trusting the browser

The curl command requests headers only and skips most of the page body. Review Server and any LiteSpeed-related lines in the first twenty lines of output. Those fields show which stack actually answered the request. Paste both command outputs in a ticket if you want us to confirm which side you are on.

Check www, the apex, and IPv6

People often move www or the bare domain and forget the other name. Run dig against both so you catch a half-finished cutover before you cancel anything. A leftover AAAA record at the old host can win on dual-stack phones and laptops. Align AAAA with the new host, or remove it if you are not using IPv6 yet.

WHOIS only names the registrar. NS records tell you who runs DNS. The A record tells you which web box answers the site. Three different companies in that chain is normal. Do not cancel the old account until the headers agree with the new IP and your mail clients agree as well. If the A record looks right but the headers still look wrong, you may simply be waiting on TTL.
