[Resolved] Control Panel, Email and Websites

We are currently experiencing issues where some customers are unable to access the control panel. This has been caused by high load on one of our Linux hosting servers.

This high load can also cause websites to load slowly and email to be delayed.

Our head of systems is investigating the issue and we will update this post when we have more information.


Email and website traffic is now working normally however control panel access is still producing errors under some conditions.
We are continuing to investigate.


Customer who were unable to access the control panel will now be able to sign in.

Sorry for any disruption this has caused.

Spoofed emails from “MyFax.com”

This afternoon we’ve received reports of customers receiving lots of junk mail supposedly from “myfax.com”.

Each email contains a link to a website that attempts to install a virus on the visitors computer.

If you receive an email that appears to come from “[email protected]”, please delete it without clicking on the link contained within.  If you have already clicked the link, we strongly advise you to scan your computer with an up-to-date virus scanner as soon as possible.

In the meantime, on all our shared hosting servers and our Mailscan spam scanning service, we have blacklisted the myfax.com domain-name.

Resolved: Control Panel Access

During the night a server that runs our control panel system developed a fault, our head of systems is at the data centre now to resolve the issue.

Website and email services are still running as normal but access to the control panel to make any changes is currently unavailable.

We will update as soon as more information is available.

Update…
The server is now responding after a restart and the control panel is available once again.

Critical Security Update Information

Overnight, a critical security flaw & patch in a commonly used Unix-based software package called bash was announced.

We advise that all our customers who have Linux/Unix based servers update their software as soon as possible in order to fully protect their systems from potential threats.

Email delivery issues

Early this morning we discovered a customers out-of-date WordPress installation on one of our servers had been compromised. The compromised website was then used to send out large amount of junk email.

As soon as the problem was discovered, the website was disabled and all remaining junk email removed from any outbound queues.

Unfortunately, as a result, a few external DNS Blacklists (RBLs) have temporarily listed the affected server.  We have requested removal from these RBLs and are waiting for the blocks to be removed.  In the short-term, some customers may find some emails to certain providers are temporarily rejected until the blacklists are fully removed.

RESOLVED: Upstream network issues

Update 11:05am:

We’ve received an update from our network provider letting us know that the problem has now been resolved.  We can also see connectivity on our test probes are now succeeding once again.  Our provider is currently monitoring the situation and are investigating the root cause of the issue.


 

Update 10.40am:

Engineers are still working to resolve the problem. We will update you as soon as we have further information.


A global transit network that our upstream provider uses is currently suffering from intermittent network issues.  Our upstream is currently working hard to resolve the issue but as a result this has caused connectivity issues with our network border.

Global routing should stabilise soon.  We will notify you as soon as we have further information.

RESOLVED: CDN Issues

A Content Delivery Network that Zebra use, Cloudflare, is currently experiencing a denial of service attack against parts of their European network.

As a result, access to the Zebra Internet Services and Domaincheck websites may be intermittent until the attacks have been mitigated.
