How many users can you effect with an expired software certificate?

Well according to Ericsson, tens of millions…

 

On Thursday last week (December 6th 2018), millions of UK O2 users were unable to text, call or use their 4G connections.
Late that same evening the Swedish technology company Ericsson, which creates most of O2’s back-end network admitted that the service downtime was due to an expired certificate! These certificates manage the way a service is provided to O2 customers and put simply, the software will not work if the certificate isn’t up to date or has expired!

This meant the certificate had to be reissued and updated which is also why users were kept offline for so long, with each Network node having to be updated manually, one by one. Ericsson CEO, Börje Ekholm stated:

 

"The faulty software that has caused these issues is being decommissioned and we apologize not only to our customers but also to their customers. We work hard to ensure that our customers can limit the impact and restore their services as soon as possible."

 

Most O2 customers were off line for almost 24 hours, causing chaos for all O2, Tesco Mobile, GiffGaff, Sky Mobile and Lyca customers, which all use the O2 network. O2 has since apologised and has given all customers credit for two days of their monthly airtime subscription.

Top 5 considerations to think about before migrating to Office 365

For small and medium sized businesses, Office 365 is a game changer with its wide range of applications and well established, versatile options to suit any business’s needs. As friendly as Office 365 may be for users, there are a few factors that should be considered before making the jump to reduce the risk of time, effort and money being wasted. To help with your decision, we’ve put together our top 5 considerations to think about before migrating to Office 365.

 

Identity

With mailboxes moving to the cloud, access to these mailboxes for on premise users needs to be considered. There are various ways to do this with separate passwords, password synch and ADFS. ADFS is recommended for a fully featured single sign on experience. With this comes the need for ADFS infrastructure.

 

Email clients

It is best practice for Email clients such as Outlook to have the latest updates installed, to maintain Office 365 hybrid functionality.

 

Shared calendars:

In a hybrid environment, shared calendars across premises (O365 <-> On Prem Exchange) can only have read permissions and not write permissions. Therefore it is best practice to migrate teams who share calendars at the same time.

 

Backups:

Although Office 365 is designed in a high availability manner, data is not backed up; meaning deleted user data is not recoverable. It’s worth considering looking into 3rd party backup solutions or using Office 365 litigation hold to retain all data.

 

Active Directory UPN:

Ensure the AD UPN matches the primary O365 SMTP address to ensure a seamless logon when it comes to Single Sign On. If they don’t match it’s worth considering changing the UPN name.
