A premier email validation service provider

Utilising the latest in A.I. technology, ZeroBounce supports businesses to increase their revenue and customer base by removing bounces and non-human addresses from their email databases. ZeroBounce helps widen communication reach to end-users rather than bots and provides full insight on the health and hygiene of email data with 98% accuracy guaranteed. As a global provider they need to maintain 24/7 uptime to provide validation around the clock, across the globe as downtime would affect both their customers and their own business. At the same time they needed to protect against attempted cyber attacks due to the sensitive and valuable nature of the data they process.

The challenge

ZeroBounce required a 10Gbps connection that could be delivered across 2 continents and with business grade continuity back up in place. With MPLS solutions in Bucharest and New York, they also needed to ensure the ability to operate a live switch at any point in time between these 2 locations to ensure 100% uptime. An anycast ISP solution was needed to ensure ZeroBounce could deliver required workloads as close as possible to each customer location. At the same time being able to ensure a secure passage of data with DDoS protection designed to mitigate against the most advanced attacks.

Key points

  • Dual switch enabled redundancy to deliver 100% uptime in 3 years since deployment
  • 10Gbps resilient connection
  • Fully bespoke solution to deliver hybrid cloud, enabling customer to retain use of existing infrastructure
  • Industry leading lead-time, delivered in under 20 days

“Guaranteeing the necessary bandwidth to enable replication and transfer between our 2 main sites had been something of an issue, our previous supplier struggled to deliver. M247 implemented a hybrid cloud solution that utilised existing servers, reduced costs and guaranteed 100% uptime.”

Our solution

A hybrid cloud solution delivered in industry leading timescale, enabling 100% uptime

ZeroBounce now have a fully redundant solution delivered over 2 continents, with the ability to load-balance the workloads between the 2 locations, live, without any downtime. This maintains 100% uptime not only on the general infrastructure, but also on the DNS infrastructure due to Anycast setup and on VMs level due to live migration and dynamic resource allocation capability.


In the 3 years since working with ZeroBounce, M247 have also installed a small IaaS in 8 more locations across the world, including Europe, Asia and America.


2 fully redundant private clouds over 2 continents

M247 implemented 2 private clouds for ZeroBounce, one based within New York and the other in Bucharest. Both were fully redundant based on Dell hardware and with a low latency MPLS between the 2 POPs.


Utilising a combination of VMWare and Dell EMC hardware, M247 were able to provide ZeroBounce the dynamic allocation needed in terms of compute and memory resources and the ability to move VMs from across continents without any downtime – creating a live migration environment for upgrades.


M247 installed 2 switches for redundancy purposes that could handle both layer2 and layer3 and provided to the customer uplinks required to all Tier 1 providers in the region. This meant it was possible to benefit from connections across multiple suppliers, including M247 private peerings, which therefore allowed the network traffic to choose the best possible route at all times.

“M247 were able to help us to utilise our existing infrastructure to protect investments the business had already made. Our key issue concerning the ability to migrate high volume of traffic between two different continents whilst ensuring 100% uptime is now no longer a concern and we have peace of mind that we have a fully resilient and redundant infrastructure”
