Aptos resumes operation after 5-hour outage that ‘impacted’ transactions

October 19, 2023 Coin Telegraph

Aptos suffered a five-hour outage, coincidentally in the same week that the network launched this time last year.

Layer-1 blockchain Aptos Network has managed to bring its network back to normal operations after a lengthy five-hour outage that saw transactions on its network “impacted."

According to the Aptoscan network tracker, on-chain transactions on the Move language-based blockchain were halted 11:11pm UTC on Oct. 18 at block 104621314 — down for more than five hours.

Aptos seemingly confirmed the outage with a post on X (formerly Twitter), noting:

“Your energy for Aptos One was so electric, you cut the lights!”

At the time, the team added that “transactions on the network have been impacted” and they were “working diligently” to resolve the issue.

Your energy for Aptos One was so electric, you cut the lights!

What that means at the moment is that transactions on the network have been impacted. We are working diligently to resolve the issue and will keep you updated upon completion.

The outage then led crypto exchanges Upbit and OKX to alert users about maintenance for the Aptos network, adding that APT deposits and withdrawals were temporarily suspended.

Before the outage, Aptos Labs posted a birthday message saying, “It's been a year since Aptos Mainnet burst onto the scene.”

Aptos, a heavily VC-backed project that launched on Oct. 17, 2022, was built by former Meta employees who worked on Facebook’s Diem blockchain.

It may be outage season as Aptos is not the only chain to go down recently.

On Oct. 19, the Theta Network team stated that a recent node upgrade created an “edge case bug” that caused blocks on the main chain to stop producing for several hours.

It added that a fix had been implemented and the network was operating normally again.

In September, the Coinbase layer-2 network Base suffered its first major outage since the launch in the previous month.

WhatsApp down again? Google Trends spike after the outage

As WhatsApp goes down once again, there are a number of alternative platforms that are popular alternatives in the cryptocurrency space.

Some two billion WhatsApp users were left without service on Oct. 25 as the biggest messaging application worldwide went offline. Meta, the owner of Facebook and WhatsApp, is yet to clarify what led to the outage.

Users took to social media platforms like Twitter to share hilarious memes about the outage, with many flocking to alternative social media platforms to find out if they were alone in their lack of service. A similar situation took place in October 2021, with Facebook, Instagram and WhatsApp going down for more than 24 hours due to a “server configuration change.”

WhatsApp is down. #Bitcoin never goes down.

This time around, the outage was fairly short-lived, with WhatsApp restoring messaging services within a few hours of the initial outage. Nevertheless, questions about alternative messaging applications came to the fore once again.

Google Trends data highlights the surge in searches relating to WhatsApp around the globe on Oct. 25 as users tried to find out what had happened to the world’s most popular messaging app. Singapore, United Arab Emirates, Italy, Netherlands, Pakistan and South Africa were among the countries with the highest number of WhatsApp-related queries following the blackout.

The cryptocurrency community has long held privacy and encryption in high regard, and as such, a number of WhatsApp competitors have been endorsed as growing alternatives.

Telegram has grown its user base steadily over the past few years, with founder and CEO Pavel Durov pinning the platform’s user base at 700 million users in October 2022. Telegram allows users to send end-to-end encrypted messages, photos and videos, share files, and create large groups or channels of up to 200,000 people for broadcasting purposes.

Signal commands a user base of some 40 million people around the world, and its privacy features are touted as industry-leading. Its open-source, end-to-end encryption means that Signal and third parties cannot read or listen to a user's messages or conversations.

Discord is a growing player in the instant messaging app space, already popular among gamers as a major voice-over-IP service. The platform is touted to serve over 140 million users that make use of its voice and video calls, text messaging, media and file sharing capabilities and server hosting.

Line is another alternative messaging service used by some 178 million users across the East Asia region. It integrates text messaging, voice and video calls with a bouquet of services, including a wallet app, gaming and music streaming services.

A decentralized alternative that bypasses the need for central servers or services is also an option. Keet, developed by Bitfinex and Tether-backed development firm Holepunch, offers a desktop-based peer-to-peer messaging application for text and video calling.

Celo network back online after almost 24-hour outage

July 15, 2022 Coin Telegraph

It was the first time the Celo mainnet had gone down in more than two years.

Proof-of-stake-based blockchain Celo has been suffering from an on-and-off network outage lasting 24 hours, though the blockchain appears to be up and running again now.

Celo is an open-source blockchain that enables users with phone numbers to make payments with crypto by using their phone numbers as a proxy for public keys.

Celo updated its Twitter followers after the network came back online, noting it was the network’s first outage since the mainnet launch on April 22, 2020, and that it has begun a “thorough and expedited technical analysis” to get to the bottom of the issue.

The protocol made the initial announcement that the network had stalled on July 14 at 12:04 am (UTC) at block 14,035,019, assuring that “all funds are safe.”

It resumed around nine hours later for several minutes before pausing again at block 14,035,045.

As at the time of writing, the network appears to be up and running again following an upgrade of its validator nodes to version 1.5.8, according to a Celo block explorer.

Update: Celo validators have resolved the network’s first outage since mainnet launch on April 22, 2020. A thorough and expedited technical analysis is ongoing and details will be readily shared with the Celo community.
— Celo (@CeloOrg) July 15, 2022

On the protocol’s Discord channel, one of the network’s validators with the username “Dee” said they saw the latest outage as “part of the growing pains” of the network but that they remained confident in the fundamentals as it was the first network halt in over two years.

“Even Visa had some network outage over the past two years despite being a market leader in payments for over 60 years.”

The Celo protocol’s whitepaper claims that it enables users to send payments “as easy as sending a text message.” The network touts an average block time of five seconds, is Ethereum Virtual Machine Compatible, and supports smart contracts and decentralized applications.

The Celo network is also the protocol behind three stablecoins — Celo Dollars (cUSD), Celo Euros (cEUR) and Celo Reals (cREAL) as well as its native token Celo (CELO).

Earlier this week, the Helium network suffered a four-hour outage due to validator outages from a software update, causing delayed transaction finality.

On June 1, the Solana network suffered yet another outage, causing block production to halt for four and a half hours. It was one of seven network outages over the last 12 months.
