My mother-in-law fell for a love scam last year. Luckily we caught it early and no money was lost, but I was surprised how difficult it was to convince her it was a scam despite the obvious signs and family and friends all telling her it wa

Ah, good to know, I hadn't seen that V2 update. Looks like a min 5m inactivity to auto-pause (i.e., scale to 0), and any connection attempt (valid or not) resumes the DB.

This was true for RDS serverless v1 which scaled to 0 but is no longer offered. V2 requires a minimum 0.5 ACU hourly commit ($40+ /mo).

Yes, we've been testing volume attachments every 5m since start of the year, and have experienced 100-150 attachment failures per volume type in that time frame during multiple events (most recently last week): https://cloud

I'm working on graduate research evaluating AWS control and data plane performance. EBS volume attachment is typically ~11s for GP2/GP3 and ~20-25s for other types. 1ms read / 5ms write latencies seem high for 4k blocks. IO1&

Lambda create-function control plane operations are still failing with InternalError for us - other services have recovered (Lambda, SNS, SQS, EFS, EBS, and CloudFront). Cloud availability is the subject of my CS grad research, I wrote a qu

For networking, the site only reports uptime % for zonal, regional, cross-region or cross-cloud tests. It excludes last mile network tests as those fail frequently due to many hops and endpoint unreliability (we use Ripe Atlas and Globalpin

For data and control plane I can determine the issue from the API request/response logs (i.e., network timeout, 5xx, etc.). Network tests are trickier and we don't have a great way to validate failure cause each of those events (i

There is lot of statistical and empirical data on this topic - MTBF estimates from vendors (typically 100k - 1m+ hours), Backblaze and Google drive failure data (~1-2% annual failure rate), IEEE and others. With N+1 redundancy (backup serve

If have a global user base, depending on your workload, a simple CDN in front of your hardware can often go a long ways with minimal cost and complexity.

As someone who spent 5 years attempting to get through zoning including a purely subjective “design review committee” in one of these affluent cities, I applaud this. While I agree with the desire to preserve the character and uniqueness on

Sounds like an L1 or malfunctioning L2. I’d never revert to ICE in cold weather climates. Handling is great and ability to preheat (without idling) is a wonderful convenience on cold mornings.

+1 Bought a used X with FSD and learned the hard way to only use on freeways and highways in simple driving conditions or traffic. Even then I’m on constant alert for phantom braking. I can’t understand the $12,000 price justification.

When did you last use PHP? It's not the PHP of 15 years ago. It scales fine when properly written and deployed.

+1 for iCloud+. I moved 3 business/family domains and shutdown my G Suite legacy account with no issues, and no extra cost (already paying for iCloud). Can't beat $0.99/mo for 50GB shared on up to 6 accounts.

AWS Lightsail is a possible workaround for bandwidth heavy simple workloads. The smallest $3.50/mo instance (t2.nano behind the scenes), comes with 1TB outbound bandwidth - equivalent of about $90 for the same in EC2 excluding the inst

I’d be interested in your take on AWS Outposts - do you see potential in this type of offering?

Perhaps, but on many pilot's knees will be a digital touchscreen kneeboard which having learned with paper approach plates and map books myself was a godsend.

I suspect they are bottlenecked on CPU - most of these instance types are capable of higher throughput than they've captured, but you'd need more than 1 Iperf process to measure it on Azure.
