My wallet says it needs another 9512 blocks to fully sync with total of 2000301 but from what I can see from securepayments pool they are currenctly mining block: 1990829: 2016-01-30 09:14:58 GMT-5 are we on a different chain or something?

It does indeed seem that the chain forked sometime back in November 2015 and no one noticed until now. It also appears to have been maliciously done..

The chain forked at block #1979437.

Block #1979436 is identical on both chains, but #1979437 differs. Here is block #1979436 from the two chains. Note how the "nextblockhash" differs.

Here is block #1979437 from both chains. Notice the timestamp on the block between the two chains:

The timestamp on block #1979437 from CHAIN B is Fri,13 Nov 2015 11:02:35 GMT while on CHAIN A it is Fri, 13 Nov 2015 11:08:42 GMT. Block #1979437 was stale on CHAIN A, this is normal and eventually CHAIN A will catch up when the block propagates and the 'correct' chain is activated.

However 20 minutes later block #1979438 is extracted on CHAIN B, but on CHAIN A #1979438 is extracted only 13 seconds later. Odd huh..?
Block #1979437 from CHAIN B hasn't propagated after 20 minutes.

Things get even more strange at block #1979439. On CHAIN B this block is extracted almost 3 hours later at Fri, 13 Nov 2015 14:16:59 GMT! While CHAIN A is moving along at a normal pace having this same block extracted only 4 seconds later at Fri, 13 Nov 2015 11:08:59 GMT.

Looking further, it's quite clear what is happening. Look at the log from CHAIN B:
