The forums have returned to the veeeeeery slow load times these past few days, with 10, 20, even 30 seconds to load a single page not uncommon. Those numbers are fine, but they should read in milliseconds, not seconds.
As well as Adobe sites, I have had this happen with other sites over the past few days
I once asked the IT staff at my work (branch campus of a University, with "about" 5,000 staff & student email accounts at any given time) and was told that the Barracuda hardware/software used here captures over a million spam emails a year
Based on that... I would say that any "new" spam wave around the 'net will cause problems for everyone, including Adobe
I don't remember any Adobe employee actually saying WHAT is used to block spam... but past problems have "sort'a" indicated that whatever Adobe is using, it is not very effective
So... we have floods of spam all over the 'net that cause problems, and seemingly not very good anti-spam hardware or software at Adobe, resulting in periodic slowdowns
There was mention made a few weeks ago that "something" was going on with the forum software, but nothing for the past week or two on that front
