but never really thought about it, that advertisers sent their adverts to the webmasters who incorporated it into the pages. It never occured to me that the graphics, video and possibly sound were merely linked in from a third party server.
It does kind of make a mockery of spending all that money on new servers earlier this year if its still being dragged down by someone else's machines.
Some of the errors may have been caused by the load balancer on the server cluster. This site isn't the only one running - we have lots of other company sites on the same servers.
We're constantly looking at ways to improve/maintain site performance, but often there are errors which are - on the face of it at least - unrelated to the site, and they can be difficult to track down.
