Hosted Email: Disabling TLS 1.0/1.1 support in January 2022

We take the security of your confidential data very seriously which is why we take proactive steps to adopt modern security and phase out older protocols over a period of time.

Back in 2020, we enforced encrypted connections on our Hosted Email platform. This meant that all connections had to be encrypted, keeping your emails safe in transit. You can read more about this here.

TLS is the successor to SSL although the term SSL is often still used to describe TLS. On January 31st 2022 at 9PM UK time we will be disabling TLS 1.0/1.1 support on our Hosted Email platform. This will mean that all connections will require TLS 1.2 or higher. TLS 1.0 and 1.1 are deprecated, deemed insecure and should be avoided to prevent the compromise of your private emails.

All modern mail clients and our Roundcube webmail already support TLS 1.2 and the vast majority of our clients will not be affected. Our latest investigation showed that 2.2% of connections used TLS 1.0, and 0.1% of connections used TLS 1.1. You can read more about our recommended mail client settings here.

If your mail client does not support TLS 1.2, we recommend that you check out Mozilla Thunderbird. It is free, open source, very easy to use and the client used by most team members at Anu: https://www.thunderbird.net/. We have a handy guide available for customers here.

Another alternative is to use our Roundcube Webmail: https://roundcube.anu.net/ – recent updates have brought in a new, modern web interface which works seamlessly across all devices (PCs, Laptops, Tablets and Phones).

We will be contacting affected customers directly over the next 8-12 weeks to make them aware and provide assistance where necessary.

If you need any further help or advice, please do not hesitate to contact us by emailing support@anu.net.

Upcoming USA1 datacenter migration

What is happening?

Over the coming weeks we will be migrating customers hosted out of our usa1 (Chicago) datacenter to a new datacenter facility which is also located in Chicago approx 2 miles away.

Why?

The new facility offers us higher power availability, better connectivity and more redundancy. We are also taking this opportunity to complete the roll-out of improved firewall and encryption subsystems on our virtualization hypervisors to further improve our cyber security defenses.

What is the impact?

Affected customer VMs will be migrated one by one to new hardware running in the new datacenter. Both facilities are connected by a VLAN which will facilitate seamless transition of IP traffic. No IP renumbering or other changes will be required. Once migration is complete you can expect lower latency, faster performance and better security.

Migration will require a brief disruption while we sync changed data and reboot VMs on new hardware. We will schedule migrations with affected customers individually at the most convenient time slots.

Questions?

Please contact support@anu.net if you have any questions about this migration.

How to check if your IP address is blocked by our firewall

Our Hosted Email and Web Hosting services are protected by multiple layers of security systems, one of which is a brute force attack detection mechanism. A brute force attack is when a malicious user keeps trying to access your account over and over again using commonly used passwords or by guessing what your password might be. Blocking this kind of attack is a very effective way of protecting your sites and email accounts from malicious access.

Every now and again it happens that a legitimate user forgets their password or mistypes it a few times and ends up blocking themselves. This can be very frustrating, so to make your life easier we have build a little utility that you can use to check if you’ve been blocked by our firewalls, and you can even use it to unblock yourself immediately.

To check your IP address if it’s blocked on any of our servers just visit https://blocked.anu.net/

Once loaded you should be able to see something like the picture below

NOTE: IP address is auto detected so if you want to check an IP address from a different location, just replace the detected IP address on the search box with the IP address you want to check.

If you are seeing “Not Blocked” next to all the servers then that means you are not blocked by our firewalls. You should be able to access your sites and email accounts.

If you are seeing one of the server is showing as “Blocked” in red letters, then you can just click on “Unblock IP Address” button to unblock yourself.

If you are still having difficulty accessing your website or email address, or if you encounter any difficulties with the self service unblocking tool, please do not hesitate contact us via live chat or by email to support@anu.net.
