So, after facing a couple of issues with the old server, last night I finally managed to migrate my witness server to a more powerful one.
My witness server is now powered by a quad core Intel Xeon L3426, with 16GB RAM, and 2 1TB HDDs in RAID1.
Everything works fine, and following the lead of other witnesses, with more power, I am thinking to increase the APR to 1%, as the price of SBD is around $1.
For the steem price feed, I am using @someguy123's steemfeed-js.
That's all for now
