Captain Ned wrote:The slowness comes and goes and is not ad-related. It seems to me as if the server-side load-balancer refers calls to something that isn't working, as a series of refreshes eventually brings the site up in normal time/speed (i.e. cycling through the load-balancer destinations).

However, if more data can be provided, that'd be helpful:
- Does your browser read anything in the status bar, like "waiting for X"?
- Is this site-wide or related to a specific section?

Switched to the provided Comcast ones (those are national, BTW), and saw the issue as described. Resolution calls stalled out, primarily on ads.

At that point (several years ago) the Internet routing tables at that site were getting an update every 1-2 seconds.

Whereas I was having the issue using OpenDNS over Comcast.

Arvald wrote:Yup. Turned up at the office and my contact took me to meet his manager. I shook his hand and he then held out his hand and said "Passport please". I just laughed it off, but later my contact told me he was only part jokingSo? He was likely fixing it so they could watch it over IPTV, not broadcast... World Cup is what? every 4 years?
