Your website is ready on its new server. To bring it back online, change two nameservers on your domain. It takes about 2 minutes, and the website and its security certificate connect automatically.
Your domain was bought through Exabytes, so this is the only place you need to change anything.
billing.exabytes.sg → log in → Domains → My Domains → click sgcommercialhub.com → Nameservers
Can't log in? Use "Forgot password" on the Exabytes login page with the email you used to buy the domain.
Delete anything in Nameserver 3, 4 and 5 if those boxes have something in them.
You should see these in the boxes before you change them:
ns1.siteground.net
ns2.siteground.net
That's it. Nothing else needs to be changed.
The website comes back online by itself, usually within an hour (at most 24 hours).
Once done, just reply to Julian's email so we can confirm it's live.
