Next Thursday is DNSSEC key roll-over day. It was 2010 when the root of DNS was first signed and key cracking technology moved on. The update will ensure you can still trust that the domain name you see in your browser/e-mail is actually who it claims to be. All our customer systems are ready for 5PM (BST) next Thursday and should continue to resolve DNSSEC enabled domains correctly. Please let us know if you experience any issues after this time?

Publicly announced today, the latest Intel Foreshadow/L1TF vulnerability looks to us like a case of pushing performance over security in chip designs. All our customer servers are now patched to mitigate against data theft. We are awaiting a statement from +Mythic Beasts Ltd on their protection of our cloud servers against other un-patched customers. If you have cloud services, please check with your provider to determine how they are keeping your data safe from others.

Congratulations +Canonical on the latest Long Term Support release of Ubuntu. We are now beginning our work to bring this to our customers later in the year, ensuring they are secure and supported through to April 2023. We are hoping to add many other enhancements to our service offering at the same time so, if you have any requests, now is a great time to let us know?

We have so far avoided commenting on the Spectre and Meltdown processor vulnerabilities unveiled at the beginning of the year due to the shambles +Intel have made of patching the microcode in their processors, used by most of us. All our customer Linux servers have been patched, un-patched and re-patched at Intel's request but we are still awaiting their solution for the majority of processors!

Now it is +Microsoft's turn with their latest Intel endorsed solution becoming available from 13th March as part of the monthly Windows security updates. However, you will only be protected if your anti-virus supports this. For our managed customers running +Dr.Web you will be supported but must ensure you reboot when requested for Dr.Web updates.

Remember you are only protected, regardless of what you run, by applying updates as soon as they are released. When a restart is requested, protection is not effective until this is completed. Any questions, please just ask?

A vulnerability has been discovered in the way WiFi devices and their access points share encryption keys. This makes it possible for someone within range of your WiFi to decrypt your private data. +MikroTik have confirmed that our customer routers already have the fix.

As the attack is primarily aimed at the devices connecting it is important that all your devices (PCs, phones, printers, Smart TVs, CCTV cameras, watches and possibly even your cars!) are also updated. Patch as soon as a security update is offered and remember that it may not be effective until you restart your device.

If you have home Wi-Fi range extenders or Access Points (even Sky Q boxes!) these will need updating too. If you are unsure of how to do this contact us with the make and model of the device and we'll find out for you?

Thanks to our partnership with +Dr.Web our customers were protected during the recent WannaCry outbreak. It pays to remain vigilant though. May we remind you that only documents stored on network drives are included in our regular off-line server backups? Anything else (including your desktop and on-line cloud/sync drives) may be lost if you happen to fall victim to one of these scams. Be safe and check where you are saving your files today!

Which? have recently surveyed 1,800 broadband users in the UK and concluded, like us, that +Zen Internet provide the best service. We're happy to continue working with them for the benefit of all our customers...

Many of our customers will now have heard of the security incident being referred to in the press as Cloudbleed. This was an issue where Cloudflare (who's services most of you will have used but never heard of as they accelerate web content in the background) disclosed information that would not normally be seen. They did an excellent job of identifying, mitigating and fixing the issue but it is possible some accounts may be compromised as a result. Two of our suppliers (BHost and Plex) have confirmed they use Cloudflare and between us we have taken the necessary action (if in doubt change you password!) to ensure our customers are not impacted.

If you would would like to check whether any of the web sites you visit are impacted, there is a full list at https://github.com/pirate/sites-using-cloudflare and a handy Google Chrome Extension to check your bookmarks at https://chrome.google.com/…/egoobjhmbpflgogbgbihhdeibdfnedii
