[Comtec Announce] [Core Network] Informational Notice 18th December 2018 - Barclays

[David Croft]

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.

Regards

David Croft
