Yesterday afternoon, Copernica disabled file downloads upon the discovery of a security risk by one of our users. The reporting user was able to download random files by manually altering URLs. To prevent abuse, all file downloads were disabled completely on the spot.
To accomodate future growth, Copernica has made significant changes to its network architecture over the past months. The most importants aspects have been to deploy a full 10Gbps over fiber network core and to double the bandwidth on the network's uplinks to the Interweb. The entire process, from design to implementation, has taken roughly four months. The final switch to the new network components was made on September 24.
Sounds awesome, but what does it all mean?
The 'old' network architecture had almost reached its limits with regards to the size of the network, meaning that at some point in the not so distant future, server capacity could no longer be expanded. With the new architecture in place, Copernica can provide its customers with ample computing power for years to come.
The network can now be connected to third party cloud providers without the data having to traverse the Interweb. This provides even more flexibility: server power can now be added by adding physical servers to Copernica's own virtualization platform, but also by connecting to a choice of third party cloud providers. No more waiting for server deliveries, instant power on demand!
Another important aspect of the new setup is that it provides even better redundancy, ensuring higher availability of the software. The fact that hardware can now be distributed more freely across physical locations, means failures have less impact.
With an ever larger number of users and the launch of new services, such as SMTPeter, the volume of emails delivered through Copernica's network is on the increase every day. To prevent the pipe to the Interweb becoming a bottleneck, the bandwidth on the uplinks has now been doubled. If needed, the uplinks' bandwidth can grow out all the way to 10Gbs.
