The board undergoes maintenance during the early hours of the morning (US Pacific Time, say around 3-4 am as I usually have problems at around 11-12 in the UK) which leads to slow pages loads and error pages. There is nothing you or I can do about this and hopefully it'll be another one of those things address when (maybe more realistically if) the forums get the change that's been spoken of for a while.
