What's going on with the Testnet?

[lukew]

A few days ago I had trouble sending all the Testnet coins from my phone to development machine. Today I send some back to the phone after re-installing the app, and they've not turned up. The transaction also has 30 confirmations, however it was made about 10 minutes ago.

Has the Testnet forked and left my phone on one fork, and my dev machine using the other?

Nope, someone just turned on a lot of mining power onto testnet briefly. This tends to happen since the difficulty is so low. At one point I remember there being several blocks being mined every second.

Problem is the block that my transaction was first included in only contains one transaction, and it isn't mine.

The check transaction function in my software (which has worked perfectly during 6+ months of development) shows block 1029856 as the block it was first included in, however BlockCypher disagrees, and so does my testnet Android wallet. I'll drag the txid from the database and post it up here in a few minutes.

Edit:

Okay, something's gone a bit screwed up. I must have screwed up the block height code when I re-wrote the GUI, but the transaction still hasn't appeared on my phone, and re-syncing it hasn't helped either.

Just as I'm typing it appears, ah well, non-existant problem solved. It's been one of those days!

I also have problems with testnet.  Some transactions I sent a few days ago still show as unconfirmed in Mycelium even though they have 4800 confirmations on blockr.io.

And then I have sent a Segwit transaction.  I first sent it without fee and later resent it with 5000 Satoshi fee. That still hasn't been confirmed after almost 2000 blocks have past.  It is not displayed on tbtc.blockr.io nor on test-insight.bitpay.com (and I can't push it to blockr.io, because their push interface can't parse witnesses).

Or is something wrong with it?

I just ran that through my application and there's nothing there, it threw an exception. The transaction doesn't exist. I've actually been having issues with sending Bitcoin to paper wallets. One feature of my system is that it can print a paper wallet, then send Bitcoin to it. Sometimes it took weeks before scanning the WIF code gave a balance, others have never worked even though the transaction is there on the blockchain.
