ATTN: do not act on this task before 2019-04-22
We've switched IBM/Silverpop to use a 2048-bit domain key, but they recommend a three month phase out for the deprecated 1024-bit key, after which it can be deleted. See T210445 for more info.
This is the DNS record to be removed from the wikimedia.org zone file:
