I have had to bookmark the congestion and link report pages as I could never find links to them from the main site. It would be worth including them (more?) prominently on the Tech Support and Knowledge Base pages, unless you prefer to keep them...
It would be handy (for users as well as staff, I'd assume) for a graph to be shaded or marked in some way when a line is subject to the DLM training period. Maybe a thicker BRAS line or something similar?
The readability of the status page entries is spoiled by the verbose "Log" sections. It would look cleaner if they were hidden behind a "verbose" link or something similar.
