ANSWER: Occasionally after we’ve completed a new website migration to our VPS servers, a client will contact us saying they are still “seeing” their old site, or that loading speed hasn’t improved, or that certain errors appear (i.e. 404 error, etc). In nearly every case, this is due to slow DNS propagation. DNS is not a perfect technology — in fact far from it — and is infamous for being the “weak link” in the way the internet works.
Modern DNS technology i.e. Anycast DNS has nearly eliminated the years of issues associated with DNS, partically slow propagation of DNS changes around the world. But still there are instances of issues sometimes where a client based in perhaps a small city or whose ISP provider is a bit outdated might see slow DNS updates.
In this case we recommend installing and connecting to the web via a VPN application so that you can surf the web from various cities around the world over an encrypted tunnel, meaning that you can bypass the local DNS issues and/or data packet loss that your ISP is suffering from.
To check your DNS propagation around the world there are some free tools available:

"After being hosted on GoDaddy for years, I didn't realize how negatively it was impacting my search traffic. Soon after moving to LittleBizzy, my homepage went from page 3 on Google to #1 world-wide for my target market, and I also reached the top 3 on Google Maps, with no additional SEO work."Juliette S.
"Before moving to LittleBizzy, whenever our news website was featured on the Drudge Report, it often slowed to a crawl or even froze up during big traffic spikes. Now, that never happens anymore, and we've been able to focus on publishing more articles instead of worrying about our web hosting."Tony H.
"The research by Amazon is definitely true, because our slow WooCommerce store was bleeding sales. After LittleBizzy stabilized our performance and moved us closer to our target customers, we saw a measurable improvement in shopping cart checkouts, esp. during holidays... much better!"Mohammed H.
