Amount of miles you can buy reduced

Just seen this on the VA web site, probably been seen by most already.
"Seen a reward you'd really like but don't have quite enough miles in your account to get it? Don't worry, there is a way, because you can now top up your account by purchasing miles. Buy Miles allows you to purchase up to 25,000* miles in any calendar year, in increments of 1,000. And they're ready to be used straight away, so that reward is as good as yours.
*We have temporarily reduced the number of miles you can purchase from to 25,000 to 19,000."
