[Core Network] Informational Notice 18th December 2018 - Barclays
Posted by David Croft on 18 December 2018 04:31 PM |

A number of customers have reported an inability to access https://cashmanagement.barclays.net/ since the weekend We have conclusively proved that there is no issue on our network, even going as far as to packet capture at all of our border routers which has verified that absolutely no response is being received from 157.83.99.50 to the TCP SYN packets which initiate the connection. We have been in contact with Barclays's DDoS protection provider Akamai/Prolexic who, while unable to divulge the exact problem due to the nature of their business, have also absolutely confirmed that the issue is not on their network but with Barclays. We have reached out to Barclays through multiple channels in an attempt to reach an network engineer in the correct department to diagnose and fix this problem however as yet they have not been responsive.

Posted by David Croft on 18 November 2018 09:31 AM |

This is an advisory notice to customers still running on PHP 5 versions. Start date: Saturday, 29th December 2018 Start time: 00:00 GMT (UTC+0000) End date: Sunday, 30th December 2018 End time: 23:59 GMT (UTC+0000) Purpose: As previously announced, all PHP 5 versions are end of life and PHP 5.6 will stop receiving security updates after 31st December 2018 [1]. All remaining websites on shared hosting running PHP 5.6 will be upgraded to PHP 7 during this maintenance window. Customers with dedicated servers will not be affected, although they are strongly advised to upgrade as PHP 5.6 will receive no further security support and we will be unable to support it. Services affected: Shared web hosting customers running PHP 5 versions. Impact: HIGH - Customer websites will be upgraded to PHP 7 and this will entail a short outage of the website as well as potential ongoing disruption if the software is not compatible with PHP 7. As this contains a major software version upgrade, this e-mail serves as 30 days notice of a change to the technical functionality of the Service that does not diminish the Service under clause 2.5 of the Master Services Agreement. Action Required: We recommend that customers verify in advance that their software is compatible with PHP 7 and if necessary upgrade it [2]. Regards, David [1] https://secure.php.net/supported-versions.php [2] https://secure.php.net/manual/en/migration70.php Read more » | |
