Hello Stellar Developers,
We've decided to push back our testnet reset to February 27th, 2019 in order to allow us more time to build in warnings to the reset date within Stellar's developer tools (Horizon, Friendbot, etc.). We'll continue to remind developers as we get closer to the date.
As always, you can read about our best practices and testnet reset schedule here: https://www.stellar.org/developers/guides/concepts/test-net.html#best-practices-for-using-testnet
