If you are one of the many who set up a full node, taking advantage of the $19/yr special pricing at weloveservers.net, you're probably aware that the blockchain is soon to outgrow the 30-GB disk storage capacity of that promotional offer.

When my three nodes reached 90% of storage capacity, I corresponded with WLS to see if I could double that to 60 GB, leaving all the other specs the same.  They said, Yes, and offered a price of $2/month!  That is, instead of the promotional price of $19/year -- or, $1.58/month -- a new total node price of just $2/mo!  They structure this as a new service add-on, and they do it with a reallocation of server assets, so you don't have to stop/start or reinstall the node!  The only pricing disadvantage of the service conversion, is that you lose any credit you might otherwise have for the remaining time on your initial $19/year payment; that contract regimen just stops immediately and they start invoicing you the $2/month going forward.

As far as I can find..
This is still the cheapest price in the world for a VPS that works splendidly running a bitcoin full node!  And, you can now pay in bitcoin!

Here's the conversion process that should work for you, as it did for me:  Log in to the main web page at weloveservers.net and click on the "Let's make a Deal" link near the bottom of the page.  Complete and send the form for VPS Hosting and clearly stating your request.  This should open a support ticket on your account -- most likely with Christopher Boswell, VP Sales -- and lead to your node conversions.

NOTE: If you've not previously acquired the $19/yr special pricing for this node service, you can still get it here:
