What's even stranger is that I know for a fact that Chrome is one of the
browsers the Lloyds digital team explicitly test against.
The only event that I can see could be correlated to the date when problem
started is the fact that August 2012 is roughly when they started divesting
the customers that would later become the TSB customers.
>From a technical perspective it meant some changes to the load-balancing
configuration: the LBG stack is basically a big n-tier architecture with
firewalls, web servers, app servers, ESB servers, DB servers in a stack,
each brand of the group is given a vertical slice in the stack with a
number of servers roughly proportional to the number of customers in the
brand. So divesting the TSB customers meant creating a new vertical slice
and allocating some servers to that slice (I can't remember if it meant
re-jigging existing servers or adding new ones). In order to do that, the
load balancers at the front will identify what brand you are going to and
direct you to one server in that brand's slice. Could there be a slight
configuration glitch in the TSB slice that only affects Chrome in a weird
intermittent way? Not impossible.
