[ MAINTENANCE ] Shared Hosting Linux Plesk and cPanel server restarts.
Posted by Anthony Hogbin on 24 October 2016 11:42 AM

As you may be aware there has been a lot of press regarding the zero day vulnerability Dirty CoW this weekend.

We have been working on this since Friday - and have moved from our temporary measures to stable solutions today.

This morning a long term stable patch has been applied to our Linux shared Plesk and cPanel nodes, and a restart followed this.

As a result you may have experienced a loss of service as these machines came back up.

If you continue to have service issues - please do not assume this is related. These works have been completed now - so any residual issues are likely unrelated - so get them raised with .

If you have any questions regarding this Copy on Write vulnerability - do not hesitate to get in touch with us.

This maintenance window is now closed.

[ LOSS OF PROTECTION ] 0000-0500hrs Tuesday 27th September.
Posted by Anthony Hogbin on 23 September 2016 12:35 PM

Day: Morning of Tuesday 27th September;

Time: Midnight to 5am Europe/London;

Reason: Soft and firmware maintenance along redundant transit route;

Effect: Loss of protection to core fibre and resulting transit to DC8 / St Asaph.


DC8 is supplied by redundant geodiverse fibre feeds.

During the early hours of Tuesday 27th - our transit providers will be carrying out work on a section of our reundant leg.

They have allowed a 3 hour window of hard down while software and firmware updates are applied, services restarted and tested.

We do not envisage any effect to services what so ever - however we will lose the N+1 protection for this period.

As such no services or transit will be effected directly.


We will update on safe completion.

[UPDATE 1109]

This test had been carried out - but has not completed well.


Post testing a modular UPS/PDU dropped the load causing a core switch failure.

We will remain in loss of protection state until this has been remedied.

[UPDATE 1300]

This engineering has completed successfully, and is to be considered closed.
